=== Upgrade job snapshot API

Upgrades a previously stored {ml} model snapshot to the
current major version.
It accepts an +{request}+ object and responds
with an +{response}+ object.

[id="{upid}-{api}-request"]
==== Upgrade job snapshots request

A +{request}+ requires the following arguments:

["source","java",subs="attributes,callouts,macros"]
--------------------------------------------------
include-tagged::{doc-tests-file}[{api}-request]
--------------------------------------------------
<1> The job that owns the snapshot
<2> The snapshot id to upgrade
<3> The time out of the request. When `wait_for_completion` is `false` the timeout value is
    applied to the time it takes for the task to be assigned to a node. When `wait_for_completion`
    is `true` this timeout applies for the whole upgrade process. The default value is `30m`
<4> When true, this causes the request to not return until the upgrade is complete.
    Otherwise, the response returns as soon as the task
    is assigned to a node. The default is false.

[id="{upid}-{api}-response"]
==== Upgrade job snapshot response

A +{response}+ contains information on if the request was completed and its assigned node.

["source","java",subs="attributes,callouts,macros"]
--------------------------------------------------
include-tagged::{doc-tests-file}[{api}-response]
--------------------------------------------------
<1> Was the upgrade completed
<2> What is the assigned node if the task is not completed
