Oh, partial upgrade is the worst. Technically it’s still supported until next year as oldoldstable so it should be fine to directly upgrade if you ask me but I understand the changes affect many things and upgrade process actually check things from the previous version, so if one upgrade directly it might go bad. That’s probably why Arch Linux can get borked if you haven’t updated for a long time.
Oh I went 11 > 12 > 13. But haven’t really checked all the configs from 12 to 13, there are many new ones too.
