Clash of Clans Bases and Game Center Accounts About a month ago I bought a new iPhone. Previously, I had been playing Clash of Clans on another device on one Game Center account. When I bought the iPhone, I set up another Game Center account. I would like to sync my base from the old account to the new account so I can play on my iPhone.

How could I do this?
Use your old Game Center account for your new device too.
