Moving threads using a script

[bigfoot]

I'm having some troubles moving a threads using my own script. I can of course just change the forum ID, but then the forumcache is not up to date.

What I'm trying to do, is when my moderators click a button in a thread, that thread must be moved to a predefined section along with changing some information for the user that posted the thread. The only problem is that I don't know how to move threads properly. I have tried searching this forum, but I haven't find any threads that helped me.

Thanks in advance,
Bigfoot
