Not sure. I've been trying to transfer for a few days but something is wrong and I've done everything it says you need to do. As far as I know you will have to change names if someone has the same name. I think you can only carry a certain amount of gil over as well. The good part is that I heard once you have purchased it it only takes maybe a few minutes but I could be wrong about that. Good luck, I'm still trying to figure it out myself.
