Upgrading a domain (console)
The upgrade process is irreversible and can't be paused or cancelled. During an upgrade, you can't make configuration changes to the domain. Before starting an upgrade, double-check that you want to proceed. You can use these same steps to perform the pre-upgrade check without actually starting an upgrade.
If the cluster has dedicated master nodes, OpenSearch upgrades complete without downtime. Otherwise, the cluster might be unresponsive for several seconds post-upgrade while it elects a master node.
To upgrade a domain to a later version of OpenSearch or Elasticsearch
-
Take a manual snapshot of your domain. This snapshot serves as a backup that you can restore on a new domain if you want to return to using the prior OpenSearch version.
-
Go to https://aws.amazon.com
and choose Sign In to the Console. -
Under Analytics, choose Amazon OpenSearch Service.
-
In the navigation pane, under Domains, choose the domain that you want to upgrade.
-
Choose Actions and Upgrade.
-
Select the version to upgrade to. If you're upgrading to an OpenSearch version, the Enable compatibility mode option appears. If you enable this setting, OpenSearch reports its version as 7.10 to allow Elasticsearch OSS clients and plugins like Logstash to continue working with Amazon OpenSearch Service. You can disable this setting later
-
Choose Upgrade.
-
Check the Status on the domain dashboard to monitor the status of the upgrade.
