Account switching from android to IOS possible?

[LilHomieTJ]

Yes it's possible, I did it.

There should still be a setting for account transfer where you go on clash on your android, then request to transfer. Then it will give you a code, then go to clash on iOS and put in the code

Voilà

It doesn't matter.
He still can use his old ios account in the apple device. The game will be there, linked to his game center account.

Not if he is on an older, unsupported device.
