Upgrade 9.2 -> current

posts: 9


there is an old site I am running on 9.2 (LTS) and I'd like to upgrade it to a current version. Customs themes will have to be put down the toilett... but what about the content from Wiki / Discussion Forum / File Gallery? How Do I migrate this? I know how to do a backup (MySQL database), but I guess a lot changed... do I have to do a gradual update? Where to start?

Thank you :-)
