Aiven for OpenSearch® version lifecycle
Learn how Aiven manages Aiven for OpenSearch® version support, end of life (EOL) dates, and what happens to your service after a version reaches EOL.
Aiven version support and upstream EOL
Aiven aims to follow the EOL schedule set by the original authors and maintainers of the open source software (the upstream projects). Once the upstream project retires a specific version, they do not receive security updates and critical bug fixes anymore by the maintainers.
Outdated services don't offer the level of protection you need, so Aiven follows the upstream project's EOL schedule to ensure that Aiven services are always running on supported versions.
Service version numbering
Aiven services inherit the upstream project's software versioning
scheme. Depending on the service, a major version can be either a single
digit or in the format major.minor. The exact version of the service is
visible in the Aiven Console when the service
is running.
Service version EOL policy
Aiven sets an EOL date for each major version of the service. This policy covers both running and powered-off services on affected versions.
EOL notifications
When Aiven sets the EOL date for a service major version:
- You receive an email notification along with instructions on the next steps.
- The Aiven Console shows an EOL alert for affected services.
- You receive email reminders monthly.
- In the month of the EOL date, you receive weekly reminders.
EOL best practices
- Use service forking to test the version upgrade before upgrading your production services.
- Upgrade to the supported version before the EOL date. This gives you time to test compatibility, resolve any issues, and plan the upgrade on your schedule.
After the EOL date:
-
If the service is powered on, it's automatically upgraded to the latest version when possible, or to another supported version.
noteIf it's not possible to upgrade a powered-on service to a supported version, the service is powered off and ultimately deleted.
-
If the service is powered off, it's deleted.
ExceptionAiven for OpenSearch® powered-off services are not deleted after their version EOL. They're upgraded and start running the new version when powered on.
