I have now two projects on phpBB 3.0.x, which are united (shared registration, one DB; most of tables are shared), but I want upgrade one of this two board to new version - 3.1.x.
On project (which I want to upgrade to 3.1) is modified board, with discussion. But the second project uses phpBB as framework and uses from first project only this tables:
In the second project I have no _forums tables etc; Its different project than phpBB forum.
So I have a question, If I upgrade the board (first project), can I have the other project on the older version 3.0 or there is any problem with logins etc?
