When changing the version of an existing cluster, either a major or a minor upgrade is performed. The difference is that a minor upgrade takes you from 5.3 to 5.6, for example, and requires no downtime as a rolling upgrade is performed. A major upgrade takes you from from 2.3 to 5.0, for example, and requires a full cluster restart as part of the upgrade process.
Bug fix releases also require no downtime when upgrading. A bug fix release takes you from 5.5.1 to 5.5.3, for example.
When upgrading from one recent major Elasticsearch version to the next, we recommend that you prepare ahead of time to make the process go smoothly. To learn more, see:
To upgrade to a later Elasticsearch version:
- Sign in to the Elastic Cloud Console.
- Click Configuration for an existing cluster in the sidebar.
In the Version section, select a new version.
If you are performing a major version upgrade, the UI will offer you a link to our migration tool that can help you determine if a direct upgrade is feasible. You might also want to consider our Best Practices for Major Version Upgrades.
- Optional: Make any other changes that are needed, such as increasing the capacity or adding plugins.
- Save your changes. The new configuration takes a few moments to create.
- If you had Kibana enabled, the UI will prompt you to also upgrade Kibana.
