merging two vbulletin boards - I need help asap!

[hitmanuk2k]

i essentially need to import one vbulletin db into another.

both databases are vb 3 beta 5.

i know someone made a script for vb2 to do this.... and i probably dont expect there to be a hack for vb3 yet, but is there a manual way of doing it. i will pay someone a bit of money if they can help me do this.

both databases are quite large btw, 3,000 members on one board, 8,000 on the other.
