Why are people still making threads for account transfers? You can do it yourself now,without stupid admin rules such as:You can't merge fake accounts with UDID Faker.

Anyways just goto identify,make sure you have an email set and identified,log onto your other device and log in with your email. It will ask for you to approve. Go to email and click the link and click that code that says it will approve the device. So then it will allow you to log in and hit transfer. It will take your account to that device and you can switch back any time. Good luck,if you have any issues,feel free to send me a forum PM.
