Works fine in 3.6.1. Only glitch I've found (which isn't new to 3.6.1, it is been this way through quite a few versions) is when dealing with the new post flag.

If I read the thread in the news forum, and post a reply, it is marked as read. Then it gets moved over to my discussion forum. When I click on the forum, the thread appears to be read already, but at the forumhome page, there appears to be new posts within the discussion forum. Sometimes this goes away by clicking on that thread again, but sometimes it appears not to clear the new post flag until I hit "mark all posts read" at the bottom of the main page.

I wonder if there is another maintenance function that would be useful in addition to "build forumcounters".

EDIT: At first glance, it looks like "build_thread_counters($threadid)" would be the function to clean up this last (minor) issue, but unfortunately it requiers the $threadid parameter, which we don't touch in the code above; just changing all forum id's at once for certain threads in the THREAD table; not then calling each one of those particular threads to build counters after making the switch.
