Pointing VB to a different database

[محروم.كوم]

Hi,


I already have VBulletin up and running and pointing to database "A".

I need to point it to a totally different database on the same server, let's call it database "B".

How do I do this?

I tried just changing the config.php file but that cased a database error and the forum wouldn't connect to database "B". What else needs to be changed?

Any advice?
