I am trying to merge to Discourse communities together. One is running on an older version so we’re trying to transfer it to a new, and updated forum. I downloaded the old forums back ups and uploaded them to the new forum, but I’m unable to restore the back up file. It says “Restore Failed. Check Logs.”
Yes, you’re right, I totally overlooked the “trying to merge” part. Good that it didn’t work @Infinite_Flight_Sims because you would have lost your new forum!
It is not necessary to update before taking a backup: you can restore a backup of an older discourse version into a newer instance. After restoring, all necessary migrations are run automatically.
The other way around doesn’t work.
