That's right, the function need more informations :

PHP Code:

$threadinfo = fetch_threadinfo($threadid);
                
                $threadman =& datamanager_init('Thread', $vbulletin, ERRTYPE_ARRAY, 'threadpost');
                $threadman->set_info('skip_moderator_log', true);
                $threadman->set_existing($threadinfo);
                $threadman->set('title', $threadinfo['title'], true, false);
                $threadman->set('forumid', $forumid_dest);
                $threadman->save();
                log_moderator_action($threadinfo, 'thread_moved_to_x', $forumid_dest); 


This work.

Thank you !
