I will run the code on my local dev site to see what I find.

Okay, this should work:

PHP Code:

global $vbulletin;
require_once(DIR . '/includes/functions_databuild.php');

$deleted = 0;
$curtime = TIMENOW;
$physicaldel = false;
$del_user = fetch_userinfo(1);
$del_forumid = '4';
$reason = 'Thema alt entfernt via cron.';

$delinfo = array(
    'userid'          => $del_user['userid'],
    'username'        => $del_user['username'],
    'reason'          => $reason,
    'keepattachments' => true
);

$countposts = ($vbulletin->forumcache["$del_forumid"]['options'] & $vbulletin->bf_misc_forumoptions['countposts']);

$query = "SELECT thread.* FROM " . TABLE_PREFIX . "thread AS thread WHERE lastpost <= " . ($curtime - 365*86400) . " AND forumid = " . $del_forumid;

$threads_delete = $vbulletin->db->query_read($query);
$mthread =& datamanager_init('Thread', $vbulletin, ERRTYPE_SILENT, 'threadpost');

while ($thread_delete = $vbulletin->db->fetch_array($threads_delete))
{
    if (!$deleted)
    {
        $deleted = true;
    }

    $mthread->set_existing($thread_delete);
    $mthread->delete($countposts, $physicaldel, $delinfo, false);
}

unset($mthread);

if ($deleted)
{
    build_forum_counters($del_forumid);
}

$move_prefixid = 'reportthread_solved';
$source_forumid = 10;
$destination_forumid = 12;

$vbulletin->db->query_write(" 
    UPDATE " . TABLE_PREFIX . "thread
        SET forumid = " . $destination_forumid . "
        WHERE forumid = " . $source_forumid . "
        AND lastpost <= " . ($curtime - 100*86400) . "
        AND prefixid = '" . $move_prefixid . "'
");

build_forum_counters($source_forumid);
build_forum_counters($destination_forumid);

I move that these double-post merges go away.
