== Upgrade {kib}
|
||
|
||
You can always upgrade to the latest patch release or from one minor version
|
||
to another within the same major version series.
|
||
|
||
For major version upgrades:
|
||
|
||
. Upgrade to the last minor version released before the new major version.
|
||
. Use the Upgrade Assistant to determine what changes you need to make before the major version upgrade.
|
||
. When you've addressed all the critical issues, upgrade {es} and then upgrade {kib}.
|
||
|
||
IMPORTANT: You can upgrade to pre-release versions of 8.0 for testing,
|
||
but upgrading from a pre-release to the final GA version is not supported.
|
||
Pre-releases should only be used for testing in a temporary environment.

WARNING: {kib} automatically runs upgrade migrations when required. To roll back to an earlier version in case of an upgrade failure, you **must** have a backup snapshot available. Use <<snapshot-repositories, Snapshot and Restore>> to back up {kib} data by targeting the `.kibana*` indices. For more information see <<upgrade-migrations, upgrade migrations>>.
|
||
|
||
Before you upgrade {kib}:
|
||
|
||
* Consult the <<breaking-changes,breaking changes>>.
|
||
* Back up your data with <<snapshot-repositories, Snapshot and Restore>>. To roll back to an earlier version, you **must** have a snapshot of the `.kibana*` indices.
|
||
* Although not a requirement for rollbacks, we recommend taking a snapshot of all {kib} indices created by the plugins you use such as the `.reporting*` indices created by the reporting plugin.
|
||
* Before you upgrade production servers, test the upgrades in a dev environment.
|
||
* See <<preventing-migration-failures, preventing migration failures>> for common reasons upgrades fail and how to prevent these.
|
||
* If you are using custom plugins, check that a compatible version is
|
||
available.
|
||
* Shut down all {kib} instances. Running more than one {kib} version against
|
||
the same Elasticseach index is unsupported. Upgrading while older {kib}
|
||
instances are running can cause data loss or upgrade failures.
|
||
|
||
To identify the changes you need to make to upgrade, and to enable you to
|
||
perform an Elasticsearch rolling upgrade with no downtime, you must upgrade to
|
||
6.7 before you upgrade to 7.0.
|
||
|
||
For a comprehensive overview of the upgrade process, refer to
|
||
*{stack-ref}/upgrading-elastic-stack.html[Upgrading the Elastic Stack]*.

[[upgrade-5x-earlier]]
|
||
=== Upgrade from 5.x or earlier
|
||
{es} can read indices created in the previous major version. Before you upgrade
|
||
to 7.0.0, you must reindex or delete any indices created in 5.x or earlier.
|
||
For more information, refer to
|
||
{stack-ref}/upgrading-elastic-stack.html#oss-stack-upgrade[Upgrading the Elastic Stack].
|
||
|
||
When your reindex is complete, follow the <<upgrade-standard, Standard upgrade>>
|
||
instructions.
|
||
|

|
||
[[upgrade-6x]]
|
||
=== Upgrade from 6.x
|
||
|
||
The recommended path is to upgrade to 6.8 before upgrading to 7.0. This makes it
|
||
easier to identify the required changes, and enables you to use the Upgrade
|
||
Assistant to prepare for your upgrade to 7.0.
|
||
|
||
TIP: The ability to import {kib} 6.x saved searches, visualizations, and
|
||
dashboards is supported.

|
||
=== Upgrade from 6.8
|
||
To help you prepare for your upgrade to 7.0, 6.8 includes an https://www.elastic.co/guide/en/kibana/6.8/upgrade-assistant.html[Upgrade Assistant]
|
||
To access the assistant, go to *Management > 7.0 Upgrade Assistant*.
|
||
|
||
After you have addressed any issues that were identified by the Upgrade
|
||
Assistant, <<upgrade-standard,upgrade to 7.0>>.
