Like Bbbkn said, you install the game on the new device; then contact Mytona customer support (from their website, NOT from within the game) and give them your old and new support codes. The deed should be done in less than a day.

if possible, jot down a few details such as level, amount of gold and rubies and experience - just in case. But when I did it recently, everything worked just fine.
