+=== Upgrading to 6.3
|
|
|
+Starting in 6.3, the default distribution includes {xpack} with a free
|
|
|
+Basic license. If you already have a Basic license, once you upgrade to 6.3
|
|
|
+it will never expire or need to be renewed. If you have a license subscription,
|
|
|
+your license and settings are preserved when you upgrade.
|
|
|
+
|
|
|
+You can perform rolling upgrades to 6.3 from OSS-only clusters running 5.6
|
|
|
+or 6.0-6.2. {xpack} Basic features will be operational once the cluster is fully
|
|
|
+upgraded.
|
|
|
+
|
|
|
+If you are using {xpack} for the first time, you must explicitly enable data
|
|
|
+collection after the upgrade to use monitoring. Set
|
|
|
+`xpack.monitoring.collection.enabled` to `true` with the `_cluster/settings`
|
|
|
+API:
|
|
|
+
|
|
|
+[source,json]
|
|
|
+----------------------------------------------------------
|
|
|
+PUT /_cluster/settings
|
|
|
+{
|
|
|
+ "persistent" : {
|
|
|
+ "xpack.monitoring.collection.enabled" : "true"
|
|
|
+ }
|
|
|
+}
|
|
|
+----------------------------------------------------------
|
|
|
+// CONSOLE
|
|
|
+
|
|
|
+To take all of the {xpack} features for a spin, you can start a 30-day trial
|
|
|
+from Kibana, or with the Start Trial API:
|
|
|
+
|
|
|
+[source,json]
|
|
|
+----------------------------------------------------------
|
|
|
+POST _xpack/license/start_trial
|
|
|
+----------------------------------------------------------
|
|
|
+// CONSOLE
|
|
|
+
|
|
|
+The 30-day trial enables you to try out the full set of Platinum features,
|
|
|
+including security, machine learning, alerting, graph capabilities, and more.
