  Official Ruling
  When the ability resolves, you choose the permanent that will be receiving the Auras. It can't be the targeted permanent, it must have the same controller as the targeted permanent, and it must be able to be enchanted by all the Auras attached to the targeted permanent. If you can't choose a permanent that meets all those criteria, the Auras won't move.
