Aw comon guys. Nobody mentioned straight slash and burn? (back up table by table, then delete from the DB one table at a time. If nobody screams, then it was safe to delete) It is so fun and exciting, especially for tables used only for the annual audit!

I'm kidding about the method EXCEPT about the part of backing up all data before anything gets deleted. Remember, safety first!
