I just recently bought new iPhone7 and I already download the app to my new iPhone but I don't know how to sync the data from my old iPhone to the new one. I have visited the dmm website (haven't visited for a long time) and I could not open the game so I don't know how to generate the sync code or password. Can the app in my previous iPhone generate the sync code as well??
