Well now I have done it. It turns out the issue was the PHP version was too low. When PHP is upgraded to 7.2 the upgrade is mostly OK, the issue now is that the upgrade mode apparently overwrote all the group information.
The groups are there, I can see them and the users, and I suspect the rest is as well but the content is not viewable. And yes, I did ignore the warning that said it would overwrite files, I expected that meant the addon data, not user data!
Is this data retrievable?
