How to integrate existing user database into vBulletin database?

[ConKien]

Macro, I have a forum and a script using the id (userid for forum and uid for the other script) When we started off, the userid and uid are the same (for both scripts to work) now they are out of synch (for some reasons).

Is there a script to re-assign forum's userid to a new userid along with their own threads and all the stuff related (linked) to userid? Can the import script do that?

Thanks,
