We have a 1 node elastic installation (7.17.14), upgrading to 8.11.3 failes wiith the error message

Caused by: org.elasticsearch.gateway.CorruptStateException: Format version is not supported. Upgrading to [8.11.3] is only supported from version [7.17.0].

Does that mean I can only upgrade to 8.11.3 when I downgrade my 7.17.14 to 7.17.0 ? Did anyone got this message too and got a workarond / solution? many thanks!

Welcome!

You need to run the upgrade assistant in Kibana.

No! Never downgrade 😉

If you had for example indices created in a 6.x version, that will tell you what you need to do next.

See documentation at [Upgrade to Elastic 8.11.3 | Elastic Installation and Upgrade Guide [8.11] | Elastic](https://www.elastic.co/guide/en/elastic-stack/8.11/upgrading-elastic-stack.html#prepare-to-upgrade)

Hope this helps.
