PHP Code:

$threaddm =& datamanager_init('Thread_FirstPost', $vbulletin, ERRTYPE_ARRAY, 'threadpost');

                $threadinfo = fetch_threadinfo($threadid);

                $foruminfo = fetch_foruminfo(NEWFORUMID);

 
                

                
                $threaddm->set_existing($threadinfo);
                $threaddm->set_info('forum', $foruminfo);
                $threaddm->set('forumid', NEWFORUMID);


                if($threaddm->errors){
                        There was an error
                        $threaddm->errors is an array of errors
                        }
                else{
                        $threaddm->save();
                        } 


Something like this should work, its untested with threads but Ive used the technique with Users so it should still work since its a datamanager. Change the 2 locations of NEWFORUMID to the forum id of the forum you want to move it to.
