Ran the upgrade according to instructions, had to remove fof-sitemap and fof-links as they where listed as incompatible. Tho after that the upgrade succeed and the forum seems to work as it should, except for two things: /admin can't be accessed, getting an unknown generic error, there's also an error when attempting to post but the post seems to be added anyway.
The forum uses a fair bunch of extensions, including redis cache which might be the problem, here's the error shown in flarum.log from bokt-redis | 0.1.0:
