OpenSearch versioning policy
Version support policy
Managed Service for OpenSearch works only with manufacturer-supported OpenSearch versions. For information about the EOL (end of life) for individual versions, see the vendor's maintenance tables.
Managed Service for OpenSearch uses two types of OpenSearch versions:
-
Major versions.
Two major versions are supported: the current and the previous one. When a new major version is released in Managed Service for OpenSearch, the oldest available major version support is discontinued.
The only exception is major version 1, which is not supported. Until major version 3 is released, only major version 2 is supported.
-
Minor versions.
The latest OpenSearch minor version is supported for each available major version. When a new minor OpenSearch version is released in Managed Service for OpenSearch, support for the previous minor version is discontinued.
Warning
- You cannot create new hosts in clusters on a discontinued version of OpenSearch.
- Clusters based on a deprecated OpenSearch version are automatically updated according to the update policy.
Update policy
A Managed Service for OpenSearch cluster running a discontinued OpenSearch version is updated to the next major version (listed as LTS).
A Managed Service for OpenSearch cluster running a discontinued OpenSearch version will be updated either to a major version, if available (listed as LTS), or the latest minor version.
The owner of the affected clusters receives an email notification on the expected automatic update. When your OpenSearch version approaches its EOL, we recommend that you update the cluster to a newer version.
