Looking for mod that will move a forum from one domain to another

[bryanb]

I am trying to move a forum from one vBulletin board to another vB board located on another domain. So far the only option I have is to import the entire board to the target domain (it's a big board ). Or copy the database and move it as well (that's 1gig).

So far I have been trying to use Impex - but it won't work unless I have the full database on the target domain. The 1 gig file is way too problematic to deal with.

This seems like a simple problem that I'm sure some people have run into if you are managing more than one board. Is there a plugin to do this? Help me please
