Souls, Diablo 3 had a very good character migration system when they released reaper of souls and XBOX ONE versions. For folks such as myself, I had to migrate my Xbox360 characters to the ONE/ROS version. I had all characters maxed out with tons of high level items and it was all transferred no problem. If blizzard can make it that easy, I'm sure bungie can figure something out. -tuna/lobo
