i have a question related to number of minor mm versions which can be skipped
during the upgrade process, to upgrade to the most current mm version.
I was migrating my Mattermost 5.29.0 Server from Ubuntu 18.04 to Ubuntu 20.04.
As recommended in the Migration Guide
I’ve first updated the Mattermost to version 5.31.0 on the SOURCE server. Afterwards installed the 5.31.0 version on the DESTINATION server, and migrated database, data and config.json to the DESTINATION server. Everything works fine so far on the new server.
- As always I’ve checked the Upgrade Guide as well as the Important Upgrade Notes
- And carefully read the changelog of 5.31.0 version
What I’ve forgot was this Note from the Upgrade Guide:
We only support a one minor version difference between the server versions when performing a rolling upgrade (for example v5.27.1 + v5.27.2 or v5.26.4 + v5.27.1 is supported, whereas v5.25.5 + v5.27.0 is not supported). Running two different versions of Mattermost in your cluster should not be done outside of an upgrade scenario.
I tried to search for a Topic which answers my questions but didn’t found anything, this is why I’ve created this topic:
- Was it wrong to upgrade from 5.29.0 directly to 5.31.0? (skipping the versions 5.29.1, 5.29.2, 5.30.0, 5.30.1 and 5.30.2)
- If so, what should i do now:
- Downgrade to 5.30.0 (or 5.30.2) on the new server and upgrade afterwards back to 5.31.0?
- I also have the database backups for 5.29.0 and 5.31.0 on the old server, but there were already some messages send on the new server (with mm 5.31.0)
Thanks a lot!
