Oh, I'm sorry about that I thought you were refering about the move itself not its effect through pokebank. Forgive me. But my answer refers to previous transfer systems such as PokeTransfer which forces you to do so before transferring them. Even when migrating you had to, but I'm assuming that they'll do the same, I mean Game Freak rarely changes. So again I apologize for the confusion. (I should've read your full questionaire, I answered only the first half of your question.)
