Merge vB > vB Script?

[Marshalus]

I know a lot of people would get a lot of use out of a hack like this, me especially.

I recently took control of another website, which had a vBulletin fourm on it, and I'd like to merge the content of that forum (users, posts, attachments, etc) into mine. Both of the forums are fairly large (1000 users with 40,000 posts each) and some of the usernames are the same, since both sites were about the same topic.

Is there any kind of script out there that can do this? What would it take to write a script like this?

I'm willing to pay the person who decides to take it on.
