hey, sorry for the late response.
nah, i had a different issue with that.
i wanted to migrate to a new server. Don't know the exact server versions right now.
But in general it was like that:
My old server was on something like 8.1.x. The fresh installed server was on 8.2.1. (or similar)
So, to make a backup and import it, it says i have to match the server version. So i tried to update to old server, but i got only the option to update to a NEWER version then the fresh installed one, i think 8.2.3, which also was a "beta". so no chance, to only update to the matching stable version to the new server...
i ended up re-installing the fresh server to an older version, and enabled auto-update.
i understand to not make the effort for subscribing to beta releases, but at least let us select to which version to update... would be nice
Otherweise, the migration worked pretty nice. i would point out a few things (DNS stuff), but in general - good work!
