Clean install for existing community

[Rolle]

With new upcoming update 4.2 I was thinking about reinstalling my community from scratch. I'm having large problems with my current community like applications not working properly, language strings missing, group permissions not saving/showing, warning points not expiring and other minor issues. I would like to do a fresh 'new' install of the suite and plugins/applications and afterwards just do SQL INSERT containing articles, forums, posts, user accounts and nexus purchases. Then probably some kind of trigger to re-index or re-cache all of the new data in the database.

Does anyone know if that is possible? I'm probably going to try it on my test install with the 4.2 beta release anyway, but I thought I'd ask if anyone else tried that kind of "migration".
