The taken King is not a part of the current gen upgrade program and as for destiny and the 2 previous expansions (tDB and HoW), all transfers had to be made prior to jan 15 2015, ie, you had to log onto your account on an xbone and download the content to that xbone prior to that date. Bungie won't reply, and if they did, they would link you to the destiny upgrade FAQ where it would describe exactly what I'm posting. Believe me, it's frustrating, I purchased tTK on both consoles.
