I suppose I just assumed it would transfer the whole table, I want to transfer users, forums, threads and posts. I'll give impex a shot, it shouldn't cause any dire problems with the original database right?
You can move your whole website to a new server, you just have to export the whole database, the OP is trying to do something a bit different than you.
You are probably going to get kicked out because you are using too much resources on your current server.
