How to import en existing vB ?

I have to import an existing vBulletin to my running vBulletin, which means I have to import the database 1 into my database 2. The problem should be to convert the id's in the tables!?

Both boards already hold a high number of topics.

Is the a known way to do this or any script that could help me?

Thx, Myrko.

Uh.. help? :(

No Idea, I thing it would be possible, but hwo to manage the same posting ID's and user ID's??

But some joke:
Maybe wait for UBB 6.0 and hope for a conversion tool for vBB. Then convert to UBB afterwards convert this to vBB. I know sounds stupid, but just want tell it. LOL :D

UBB conversion from Vbulletin? never happen, they would have to admit to vbulletin's existence for that to be released :)
