The migration is done. The only hiccup was trying to merge my users together - there’s something special about my user (because it was the user created as part of the initial install) which went horribly wrong when I tried to merge it with my other users. This meant I had to restore a backup, so apologies if you got two copies of the welcome mail. Backup restore seems otherwise fine, so that’s a nice test
I’m confident this won’t affect anyone else having users merged together - I actually tested this in dev mode 2 months ago and hit exactly the same issue with my user (and only my user), I just completely forgot about it this evening . Silly me. Obviously I’ll be taking extra care with the first few merges to do it after a backup and during a quiet period though
As ever, get in touch if you see anything odd, but the backup appears to have restored cleanly, so I think it’ll be fine.
