You have to use the same account as on your Xbox 360 to transfer the progress. but that what i found: http://www.respawn.com/forum/viewtopic.php?f=23&t=15618&hilit=Carry+over
If you have created a new Xbox Client there is no option to transfer, dont relink your Gamertag over Origin when there is a option your progress from Titanfall and the progress from other games like Fifa or Battlefield are going lost.
