{es} can usually be upgraded using a <<rolling-upgrades,Rolling upgrade>>
|
||
process so upgrading does not interrupt service. Rolling upgrades are supported:
|
||
|
||
* Between minor versions
|
||
* From 5.6 to 6.8
|
||
* From 6.8 to {version}
|
||
ifeval::[ "{version}" != "{minor-version}.0" ]
|
||
* From any version since {minor-version}.0 to {version}
|
||
endif::[]
|
||
|
||
[TIP]
|
||
====
|
||
For rolling upgrades between major versions (e.g., 5.6 to 6.8), we recommend
|
||
using the {kibana-ref}/upgrade-assistant.html[Kibana Upgrade Assistant].
|
||
|
||
The upgrade assistant identifies deprecated settings in your cluster and guides
|
||
you through the process of resolving issues, including reindexing.
|
||
|
||
We also recommend checking your <<deprecation-logging,deprecation logs>> for any
|
||
other functionality that may have changed.

[WARNING]
|
||
====
|
||
The upgrade path from 6.8 to 7.0 is *not* supported (both full cluster restart and rolling upgrade).
|
||
====
|
||
|
||
To upgrade directly to {version} from 6.7 or earlier, you must shut down the
|
||
cluster, install {version}, and restart. For more information, see
|
||
<<restart-upgrade, Full cluster restart upgrade>>.
|
||
|
||
[WARNING]
|
||
====
|
||
In-place downgrades to earlier versions are *not* supported. To downgrade to an
|
||
earlier version, <<snapshots-restore-snapshot,restore a snapshot>> taken prior
|
||
to the version upgrade.
|
||
====
|
||
|
||
{es} can read indices created in the previous major version. If you
|
||
have indices created in 5.x or before, you must reindex or delete them
|
||
before upgrading to {version}. {es} nodes will fail to start if
|
||
incompatible indices are present. Snapshots of 5.x or earlier indices cannot be
|
||
restored to a 7.x cluster even if they were created by a 6.x cluster. For
|
||
information about upgrading old indices, see <<reindex-upgrade, Reindex to upgrade>>.
|
||
|
||
When upgrading to a new version of {es}, you need to upgrade each
|
||
of the products in your Elastic Stack. For more information, see the
|
||
{stack-ref}/upgrading-elastic-stack.html[Elastic Stack Installation and Upgrade Guide].
