Transfer CoC from iOS to Android without locking CoC to iPhone
I have an unusual situation. My son has been using my iPhone for Clash of Clans, but never set up Gamecentre. As a result, I understand that his game is actually not backed up anywhere, except for the device itself.
We now have an android device (Android1) that he would like to use. I have a (different) android device (Android2) that has my game on it. I'd like to transfer his game to Android1, and transfer my game to my iPhone so that I can play on both devices (Android2 and iPhone).
I understand that in order to transfer his game, we need to link it to a Gamecentre account. We've set up a GameCentre account for him for this purpose. Once linked, I plan to use "Link a Device" to transfer his game to his own Google account on Android1. I think that part will work fine. The problem, is that I'm not sure what will happen if I log into my GameCentre account on iPhone. Will his game, which would not be linked with his Gamecentre account, also become linked with my GameCentre account?
