Migrate migration docs from 6.0 to 7.0 (#26227)

* Migrate migration docs from 6.0 to 7.0

Since we only keep one version of migration docs and master is now on 7.0, we
should migrate these so breaking changes can be added in the right place.

* Remove release notes as well

They link to the migration guides, so they have to go.

* Add placeholder notes for 7.0 so doc build is happy

-== Breaking changes in 6.0
-
-This section discusses the changes that you need to be aware of when migrating
-your application to Elasticsearch 6.0.
-
-[float]
-=== Indices created before 6.0
-
-Elasticsearch 6.0 can read indices created in version 5.0 or above.  An
-Elasticsearch 6.0 node will not start in the presence of indices created in a
-version of Elasticsearch before 5.0.
-
-[IMPORTANT]
-.Reindex indices from Elasticseach 2.x or before
-=========================================
-
-Indices created in Elasticsearch 2.x or before will need to be reindexed with
-Elasticsearch 5.x in order to be readable by Elasticsearch 6.x. The easiest
-way to reindex old indices is to use the `reindex` API.
-

-==== Numeric `to` and `from` parameters in `date_range` aggregation are interpreted according to `format` now
-
-Numeric `to` and `from` parameters in `date_range` aggregations used to always be interpreted as `epoch_millis`,
-making other numeric formats like `epoch_seconds` unusable for numeric input values. 
-Now we interpret these parameters according to the `format` of the target field. 
-If the `format` in the mappings is not compatible with the numeric input value, a compatible 
-`format` (e.g. `epoch_millis`, `epoch_second`) must be specified in the `date_range` aggregation, otherwise an error is thrown.

-==== Shadow Replicas have been removed
-
-Shadow replicas don't see enough usage, and have been removed. This includes the
-following settings:
-
-- `index.shared_filesystem`
-- `index.shadow_replicas`
-- `node.add_lock_id_to_custom_path`
-
-==== Open/Close index API allows wildcard expressions that match no indices by default
-
-The default value of the `allow_no_indices` option for the Open/Close index API
-has been changed from `false` to `true` so it is aligned with the behaviour of the
-Delete index API. As a result, Open/Close index API don't return an error by
-default when a provided wildcard expression doesn't match any closed/open index.
-
-==== Delete a document
-
-Delete a document from non-existing index has been modified to not create the index.
-However if an external versioning is used the index will be created and the document
-will be marked for deletion. 
-
-==== Indices aliases api resolves indices expressions only against indices
-
-The index parameter in the update-aliases, put-alias, and delete-alias APIs no
-longer accepts alias names. Instead, it accepts only index names (or wildcards
-which will expand to matching indices).
-
-==== Delete index api resolves indices expressions only against indices

-The index parameter in the delete index API no longer accepts alias names.
-Instead, it accepts only index names (or wildcards which will expand to
-matching indices).
-
-==== Support for `+` has been removed in index expressions
-
-Omitting the `+` has the same effect as specifying it, hence support for `+`
-has been removed in index expressions.
-
-==== Translog retention
-
-Translog files are now kept for up to 12 hours (by default), with a maximum size of `512mb` (default), and
-are no longer deleted on `flush`. This is to increase the chance of doing an operation based recovery when
-bringing up replicas up to speed.

-
-==== The format of the string-formatted ingest.timestamp field has changed
-
-Previously, since Elasticsearch 5.4.0, you needed to use `ingest.new_date_format` to have the
-`ingest.timestamp` metadata field be formatted in such a way that ES can coerce it to a field
-of type `date` without further transformation. This is not necessary anymore and this setting was
-removed. You can now simply set a field to `{{ingest.timestamp}}` in a pipeline, and have that
-field be of type `date` without any mapping errors.

-=== Java API changes

-==== `setSource` methods require XContentType
-
-Previously the `setSource` methods and other methods that accepted byte/string representations of
-an object source did not require the XContentType to be specified. The auto-detection of the content
-type is no longer used, so these methods now require the XContentType as an additional argument when
-providing the source in bytes or as a string.
-
-==== `DeleteByQueryRequest` requires an explicitly set query
-
-In previous versions of Elasticsearch, delete by query requests without an explicit query
-were accepted, match_all was used as the default query and all documents were deleted
-as a result. From version 6.0.0, a `DeleteByQueryRequest` requires an explicit query be set.
-
-==== `InternalStats` and `Stats` getCountAsString() method removed
-
-The `count` value in the stats aggregation represents a doc count that shouldn't require a formatted
-version. This method was deprecated in 5.4 in favour of just using
-`String.valueOf(getCount())` if needed
-
-==== `ActionRequestBuilder#execute` returns `ActionFuture` rather than `ListenableActionFuture`
-
-When sending a request through the request builders e.g. client.prepareSearch().execute(), it used to
-be possible to call `addListener` against the returned `ListenableActionFuture`. With this change an
-`ActionFuture` is returned instead, which is consistent with what the `Client` methods return, hence
-it is not possible to associate the future with listeners. The `execute` method that accept a listener
-as an argument can be used instead.
-
-==== `Terms.Order` and `Histogram.Order` classes replace by `BucketOrder`
-
-The `terms`, `histogram`, and `date_histogram` aggregation code has been refactored to use common
-code for ordering buckets. The `BucketOrder` class must be used instead of `Terms.Order` and
-`Histogram.Order`. The `static` methods in the `BucketOrder` class must be called instead of directly
-accessing internal order instances, e.g. `BucketOrder.count(boolean)` and `BucketOrder.aggregation(String, boolean)`.
-Use `BucketOrder.key(boolean)` to order the `terms` aggregation buckets by `_term`.
-
-=== `getTookInMillis()` removed in `BulkResponse`, `SearchResponse` and `TermVectorsResponse`
-
-In `BulkResponse`, `SearchResponse` and `TermVectorsResponse` `getTookInMiilis()` method
-has been removed in favor of `getTook` method. `getTookInMiilis()` is easily replaced by
-`getTook().getMillis()`.
-
-=== `GetField` and `SearchHitField` replaced by `DocumentField`
-
-As `GetField` and `SearchHitField` have the same members, they have been unified into
-`DocumentField`.
-
-=== Some Aggregation classes have moved packages
-
-The classes for the variants of the range aggregation (geo_distance, date and ip) were moved into the `org.elasticsearch.search.aggregations.bucket.range` 
-package.
-
-The `org.elasticsearch.search.aggregations.bucket.terms.support` package was removed and the classes were moved to 
-`org.elasticsearch.search.aggregations.bucket.terms`.
-
-The filter aggregation classes were moved to `org.elasticsearch.search.aggregations.bucket.filter`
-
-=== Constructor for `PercentileRanksAggregationBuilder` has changed
-
-It is now required to include the desired ranks as a non-null, non-empty array of doubles to the builder's constructor,
-rather than configuring them via a setter on the builder. The setter method `values()` has correspondingly
-been removed.

-=== Mapping changes
-
-==== Coercion of boolean fields
-
-Previously, Elasticsearch recognized the strings `true`, `false`, `on`, `off`, `yes`, `no`, `0`, `1` as booleans. Elasticsearch 6.0
-recognizes only the strings `true` and `false` as booleans and will throw an error otherwise. For backwards compatibility purposes, during the 6.x
-series the previous coercion rules will continue to work on pre-6.0 indices. This means that you do not need to change affected existing
-mappings immediately. However, it is not possible to create new indices from existing index templates that violate the strict `boolean`
-coercion rules.
-
-==== The `_all` meta field is now disabled by default
-
-On new mappings, the `_all` meta field that contains a copy of the text from
-each field is now disabled by default. The `query_string` and
-`simple_query_string` queries that previously used `_all` to search will now
-check if `_all` is enabled/disabled and switch to executing the query across all
-fields if `_all` is disabled. `_all` can no longer be configured for indices
-created with Elasticsearch version 6.0 or later.
-
-==== The `include_in_all` mapping parameter is now disallowed
-
-Since the ++_all++ field is now disabled by default and cannot be configured for
-indices created with Elasticsearch 6.0 or later, the `include_in_all` setting is
-now disallowed for these indices' mappings.
-
-==== Unrecognized `match_mapping_type` options not silently ignored
-
-Previously Elasticsearch would silently ignore any dynamic templates that
-included a `match_mapping_type` type that was unrecognized. An exception is now
-thrown on an unrecognized type.

-=== Packaging changes
-
-==== Configuring custom user and group for package is no longer allowed
-
-Previously someone could configure the `$ES_USER` and `$ES_GROUP` variables to
-change which user and group Elasticsearch was run as. This is no longer
-possible, the DEB and RPM packages now exclusively use the user and group
-`elasticsearch`. If a custom user or group is needed then a provisioning system
-should use the tarball distribution instead of the provided RPM and DEB
-packages.
-
-==== `path.conf` is no longer a configurable setting
-
-Previous versions of Elasticsearch enabled setting `path.conf` as a
-setting. This was rather convoluted as it meant that you could start
-Elasticsearch with a config file that specified via `path.conf` that
-Elasticsearch should use another config file. Instead, to configure a custom
-config directory, use the <<config-files-location,`ES_PATH_CONF` environment
-variable>>.
-
-==== `CONF_DIR` is no longer supported
-
-Previous versions of Elasticsearch enabled using the `CONF_DIR` environment
-variable to specify a custom configuration directory for some configuration
-files and some scripts (it was used inconsistently). Starting in Elasticsearch
-6.0.0, the usage of this environment variable has been superceded by
-`ES_PATH_CONF`, and this new environment variable is consistently used for all
-configuration files and scripts.
-
-==== Default path settings are removed
-
-Previous versions of Elasticsearch enabled setting `default.path.data` and
-`default.path.logs` to set the default data path and default logs path if they
-were not otherwise set in the configuration file. These settings have been
-removed and now data paths and log paths can be configured via settings
-only. Related, this means that the environment variables `DATA_DIR` and
-`LOG_DIR` no longer have any effect as these were used to set
-`default.path.data` and `default.path.logs` in the packaging scripts.
-
-Additionally, this means that if you were using the package distributions (i.e.,
-you have installed Elasticsearch from the RPM or the DEB distributions), you had
-not previously explicitly configured `path.data` or `path.logs`, and you carry
-over your `elasticsearch.yml` file from 5.x, then you will need to add settings
-for `path.data` and `path.logs`. To use the defaults that you were implicitly
-using previously, you should add these lines to your `elasticsearch.yml`:
-
-[source,yaml]
---------------------------------------------------
-path.data: /var/lib/elasticsearch
-path.logs: /var/log/elasticsearch
---------------------------------------------------
-
-(If you already had explicit values for either of these settings, you should of
-course preserve those). If you do not do this, Elasticsearch will refuse to
-start.
-
-==== 32-bit is no longer maintained
-
-We previously attempted to ensure that Elasticsearch could be started on 32-bit
-JVM (although a bootstrap check prevented using a 32-bit JVM in production). We
-are no longer maintaining this attempt.
-
-==== `ES_JVM_OPTIONS`is no longer supported
-
-The environment variable `ES_JVM_OPTIONS` that enabled a custom location for the
-`jvm.options` file has been removed in favor of using the environment variable
-`ES_PATH_CONF`. This environment variable is already used in the packaging to
-support relocating the configuration files so this change merely aligns the
-other configuration files with the location of the `jvm.options` file.
-
-==== `ES_INCLUDE` is no longer supported
-
-The environment variable `ES_INCLUDE` could previously be used to establish the
-environment used to start Elasticsearch (and various supporting scripts). This
-legacy feature could be useful when there were several environment variables
-useful for configuring JVM options; this functionality had previously been
-replaced by <<jvm-options>>. Therefore, `ES_INCLUDE` has been removed.

-* Specifying ec2 signer type has been removed, including `cloud.aws.signer` and `cloud.aws.ec2.signer`.
-
-* The region setting has been removed. This includes the settings `cloud.aws.region`
-and `cloud.aws.ec2.region`. Instead, specify the full endpoint.
-
-* All `cloud.aws.*` and `cloud.aws.ec2.*` settings have been removed. Use `discovery.ec2.*` settings instead.
-
-==== Ignoring hidden folders
-
-Previous versions of Elasticsearch would skip hidden files and directories when
-scanning the plugins folder. This leniency has been removed.
-
-==== ICU Analysis plugin
-
-The icu4j library has been upgraded to 59.1,
-Indices created in the previous major version will need to be reindexed
-in order to return correct (and correctly ordered) results,
-and to take advantage of new characters.
-
-==== Plugins should not construct `Environment` instances from `Settings`
-
-Previously, plugins could construct an `Environment` instance from `Settings` to
-discover the path to plugin-specific config files. This will no longer work in
-all situations as the `Settings` object does not carry the necessary information
-for the config path to be set correctly. Instead, plugins that need to know the
-config path should have a single constructor that accepts a pair of `Settings`
-and `Path` instances, and construct an `Environment` using the corresponding
-constructor on `Environment`.

-=== REST changes
-
-==== Unquoted JSON
-
-In previous versions of Elasticsearch, JSON documents were allowed to contain unquoted field names.
-This feature was removed in the 5.x series, but a backwards-compatibility layer was added via the
-system property `elasticsearch.json.allow_unquoted_field_names`. This backwards-compatibility layer
-has been removed in Elasticsearch 6.0.0.
-
-==== Duplicate Keys in JSON, CBOR, Yaml and Smile
-
-In previous versions of Elasticsearch, documents were allowed to contain duplicate keys. Elasticsearch 6.0.0
- enforces that all keys are unique. This applies to all content types: JSON, CBOR, Yaml and Smile.
-
-==== Content-Type Auto-detection
-
-In previous versions of Elasticsearch, having a proper Content-Type for the data in a request was not enforced.
-Elasticsearch 6.0.0 enforces that all requests with a body must have a supported Content-Type and this type will
-be used when parsing the data.
-
-When using the `source` query string parameter, the `source_content_type` parameter must also be specified with
-the media type of the source.
-
-==== Boolean API parameters
-
-All REST APIs parameters (both request parameters and JSON body) support providing boolean "false" as the
-value `false` and boolean "true" as the value `true`. All other values will raise an error.
-
-==== Analyze API changes
-
-The deprecated request parameters and plain text in request body has been removed. Define parameters in request body.
-
-==== Support custom normalizer in Analyze API
-
-Analyze API can analyze normalizer and custom normalizer.
-In previous versions of Elasticsearch, Analyze API is requiring a `tokenizer` or `analyzer` parameter.
-In Elasticsearch 6.0.0, Analyze API can analyze a text as a keyword field with custom normalizer
-or if `char_filter`/`filter` is set and `tokenizer`/`analyzer` is not set.
-
-==== Indices exists API
-
-The `ignore_unavailable` and `allow_no_indices` options are no longer accepted
-as they could cause undesired results when their values differed from their
-defaults.
-
-==== `timestamp` and `ttl` in index requests
-
-`timestamp` and `ttl` are not accepted anymore as parameters of index/update
-requests.
-
-==== Refresh requests with one or more shard failures return HTTP 500 response instead of 200
-
-Refresh requests that are broadcast to multiple shards that can have one or more
-shards fail during the request now return a 500 response instead of a 200
-response in the event there is at least one failure.
-
-==== Delete by Query API requires an explicit query
-
-In previous versions of Elasticsearch, delete by query requests without an explicit query
-were accepted, match_all was used as the default query and all documents were deleted
-as a result. From version 6.0.0, delete by query requests require an explicit query.
-
-==== DELETE document calls now implicitly create the type
-
-Running `DELETE index/type/id` now implicitly creates `type` with a default
-mapping if it did not exist yet.
-
-==== Indices information APIs
-
-Previously it was possible to execute `GET /_aliases,_mappings` or `GET
-/myindex/_settings,_alias` by separating mulitple types of requests with commas
-in order to retrieve multiple types of information about one or more indices.
-This comma-separation for retrieving multiple pieces of information has been
-removed.. `GET /_all` can be used to retrieve all aliases, settings, and
-mappings for all indices. In order to retrieve only the mappings for an index,
-`GET /myindex/_mappings` (or `_aliases`, or `_settings`).
-
-==== Requests to existing endpoints with incorrect HTTP verb now return 405 responses
-
-Issuing a request to an endpoint that exists, but with an incorrect HTTP verb
-(such as a `POST` request to `/myindex/_settings`) now returns an HTTP 405
-response instead of a 404. An `Allow` header is added to the 405 responses
-containing the allowed verbs. For example:
-
-[source,text]
--------------------------------------------
-$ curl -v -XPOST 'localhost:9200/my_index/_settings'
-*   Trying 127.0.0.1...
-* TCP_NODELAY set
-* Connected to localhost (127.0.0.1) port 9200 (#0)
-> POST /my_index/_settings HTTP/1.1
-> Host: localhost:9200
-> User-Agent: curl/7.51.0
-> Accept: */*
-> 
-< HTTP/1.1 405 Method Not Allowed
-< Allow: PUT,GET
-< content-type: application/json; charset=UTF-8
-< content-length: 134
-< 
-{
-  "error" : "Incorrect HTTP method for uri [/my_index/_settings] and method [POST], allowed: [PUT, GET]",
-  "status" : 405
-}
-* Curl_http_done: called premature == 0
-* Connection #0 to host localhost left intact
---------------------------------------------
-
-==== Disallow using `_cache` and `_cache_key`
-
-The `_cache` and `_cache_key` options in queries have been deprecated since version 2.0.0 and
-have been ignored since then, issuing a deprecation warning. These options have now been completely
-removed, so using them now will throw an error.
-
-==== IndexClosedException to return 400 status code
-
-An `IndexClosedException` is returned whenever an api that doesn't support
-closed indices (e.g. search) is called passing closed indices as parameters
-and `ignore_unavailable` is set to `false`. The response status code returned
-in such case changed from `403` to `400`

-==== Groovy, JavaScript, and Python languages removed
-
-The Groovy, JavaScript, and Python scripting languages were deprecated in
-elasticsearch 5.0 and have now been removed. Use painless instead.
-
-==== Native scripts removed
-
-Native scripts have been removed. Instead,
-<<modules-scripting-engine, implement a `ScriptEngine`>>.
-
-==== Date fields now return dates
-
-`doc.some_date_field.value` now returns ++ReadableDateTime++s instead of
-milliseconds since epoch as a `long`. The same is true for
-`doc.some_date_field[some_number]`. Use `doc.some_date_field.value.millis` to

-
-==== Removed access to index internal via the `_index` variable
-
-The `_index` variable has been removed. If you used it for advanced scoring, consider writing a `Similarity` plugin.
-
-==== Script Settings
-
-All of the existing scripting security settings have been removed.  Instead
-they are replaced with `script.allowed_types` and `script.allowed_contexts`.
-
-==== `lang` can no longer be specified when using a stored script as part of a request
-
-The `lang` variable can no longer be specified as part of a request that uses a stored
-script otherwise an error will occur.  Note that a request using a stored script is
-different from a request that puts a stored script.  The language of the script has
-already been stored as part of the cluster state and an `id` is sufficient to access
-all of the information necessary to execute a stored script.
-
-==== 'lang` can no longer be used when putting, getting, or deleting a stored script
-
-Stored scripts can no longer have the `lang` parameter specified as part of the url
-when performing PUT, GET, and DELETE actions on the `_scripts/` path.  All stored
-scripts must have a unique `id` as the namespace is only `id` now and no longer `lang`
-and `id`.
-
-==== Stored search template apis removed
-
-The PUT, GET and DELETE `_search/template` apis have been removed. Store search templates with the stored scripts apis instead.
-
-For example, previously one might have stored a search template with the following:
-
-[source,js]
---------------------------------------------------
-PUT /_search/template/my_template
-{
-  "query": {
-    "match": {
-      "f1": "{{f1}}"

-* The `terms` query now always returns scores equal to `1` and is not subject to
-  `indices.query.bool.max_clause_count` anymore.
-
-* The deprecated `indices` query has been removed.
-
-* Support for empty query objects (`{ }`) has been removed from the query DSL.
-  An error is thrown whenever an empty query object is provided.
-
-* The deprecated `minimum_number_should_match` parameter in the `bool` query has
-  been removed, use `minimum_should_match` instead.
-
-* The `query_string` query now correctly parses the maximum number of
-  states allowed when
-  "https://en.wikipedia.org/wiki/Powerset_construction#Complexity[determinizing]"
-  a regex as `max_determinized_states` instead of the typo
-  `max_determined_states`.
-
-* The `query_string` query no longer accepts `enable_position_increment`, use
-  `enable_position_increments` instead.
-
-* For `geo_distance` queries, sorting, and aggregations the `sloppy_arc` option
-  has been removed from the `distance_type` parameter.
-
-* The `geo_distance_range` query, which was deprecated in 5.0, has been removed.
-
-* The `optimize_bbox` parameter has been removed from `geo_distance` queries.
-
-* The `ignore_malformed` and `coerce` parameters have been removed from
-  `geo_bounding_box`, `geo_polygon`, and `geo_distance` queries.
-
-* The `disable_coord` parameter of the `bool` and `common_terms` queries has
-  been removed. If provided, it will be ignored and issue a deprecation warning.
-
-* The `template` query has been removed. This query was deprecated since 5.0
-
-* The `percolate` query's `document_type` has been deprecated. From 6.0 and later
-  it is no longer required to specify the `document_type` parameter.
-
-* The `split_on_whitespace` parameter for the `query_string` query has been removed.

-  If provided, `default_field` will be automatically set to `*`
-
-* The `index` parameter in the terms filter, used to look up terms in a dedicated index is
-  now mandatory. Previously, the index defaulted to the index the query was executed on. Now this index
-  must be explicitly set in the request.
-
-==== Search shards API
-
-The search shards API no longer accepts the `type` url parameter, which didn't
-have any effect in previous versions.
-
-==== Changes to the Profile API
-
-The `"time"` field showing human readable timing output has been replaced by the `"time_in_nanos"`
-field which displays the elapsed time in nanoseconds. The `"time"` field can be turned on by adding
-`"?human=true"` to the request url. It will display a rounded, human readable time value.
-
-==== Scoring changes
-
-===== Query normalization
-
-Query normalization has been removed. This means that the TF-IDF similarity no
-longer tries to make scores comparable across queries and that boosts are now
-integrated into scores as simple multiplicative factors.
-
-Other similarities are not affected as they did not normalize scores and
-already integrated boosts into scores as multiplicative factors.
-
-See https://issues.apache.org/jira/browse/LUCENE-7347[`LUCENE-7347`] for more
-information.
-
-===== Coordination factors
-
-Coordination factors have been removed from the scoring formula. This means that
-boolean queries no longer score based on the number of matching clauses.
-Instead, they always return the sum of the scores of the matching clauses.
-
-As a consequence, use of the TF-IDF similarity is now discouraged as this was
-an important component of the quality of the scores that this similarity
-produces. BM25 is recommended instead.
-
-See https://issues.apache.org/jira/browse/LUCENE-7347[`LUCENE-7347`] for more
-information.
-
-==== Fielddata on `_uid`
-
-Fielddata on `_uid` is deprecated. It is possible to switch to `_id` instead
-but the only reason why it has not been deprecated too is because it is used
-for the `random_score` function. If you really need access to the id of
-documents for sorting, aggregations or search scripts, the recommendation is
-to duplicate the id as a field in the document.
-
-==== Highlighters
-
-The `unified` highlighter is the new default choice for highlighter.
-The offset strategy for each field is picked internally by this highlighter depending on the
-type of the field (`index_options`).
-It is still possible to force the highlighter to `fvh` or `plain` types.
-
-The `postings` highlighter has been removed from Lucene and Elasticsearch.
-The `unified` highlighter outputs the same highlighting when `index_options` is set
- to `offsets`.
-
-==== `fielddata_fields`
-
-The deprecated `fielddata_fields` have now been removed. `docvalue_fields` should be used instead.
-
-==== Inner hits
-
-The source inside a hit of inner hits keeps its full path with respect to the entire source.
-In prior versions the source field names were relative to the inner hit.

-The configuration file found in the Elasticsearch config directory could previously have
-a `.yml`, `.yaml` or `.json` extension. Only `elasticsearch.yml` is now supported.
-
-==== Duplicate keys in configuration file
-
-In previous versions of Elasticsearch, the configuration file was allowed to
-contain duplicate keys. For example:

-node:
-  name: my-node
-
-node
-  attr:
-    rack: my-rack

-
-[source,yaml]
---------------------------------------------------
-node:
-  name: my-node
-  attr:
-    rack: my-rack
---------------------------------------------------
-
-==== Coercion of boolean settings
-
-Previously, Elasticsearch recognized the strings `true`, `false`, `on`, `off`, `yes`, `no`, `0`, `1` as booleans. Elasticsearch 6.0
-recognizes only `true` and `false` as boolean and will throw an error otherwise. For backwards compatibility purposes, during the 6.x series
-index settings on pre-6.0 indices will continue to work. Note that this does not apply to node-level settings that are stored
-in `elasticsearch.yml`.
-
-==== Snapshot settings
-
-The internal setting `cluster.routing.allocation.snapshot.relocation_enabled` that allowed shards with running snapshots to be reallocated to
-different nodes has been removed. Enabling this setting could cause allocation issues if a shard got allocated off a node and then
-reallocated back to this node while a snapshot was running.
-
-==== Store throttling settings
-
-Store throttling has been removed. As a consequence, the
-`indices.store.throttle.type` and `indices.store.throttle.max_bytes_per_sec`
-cluster settings and the `index.store.throttle.type` and
-`index.store.throttle.max_bytes_per_sec` index settings are not
-recognized anymore.
-
-==== Store settings
-
-The `default` `index.store.type` has been removed. If you were using it, we
-advise that you simply remove it from your index settings and Elasticsearch
-will use the best `store` implementation for your operating system.
-
-==== Network settings
-
-The blocking TCP client, blocking TCP server, and blocking HTTP server have been removed.
-As a consequence, the `network.tcp.blocking_server`, `network.tcp.blocking_client`,
-`network.tcp.blocking`,`transport.tcp.blocking_client`, `transport.tcp.blocking_server`,
-and `http.tcp.blocking_server` settings are not recognized anymore.
-
-The previously unused settings `transport.netty.max_cumulation_buffer_capacity`,
-`transport.netty.max_composite_buffer_components` and
-`http.netty.max_cumulation_buffer_capacity` have been removed.

+
+Indices created in Elasticsearch 5.x or before will need to be reindexed with
+Elasticsearch 6.x in order to be readable by Elasticsearch 7.x. The easiest
+way to reindex old indices is to use the `reindex` API.
