Pnoy,
Go to Settings on the account you want to be transferred. Then go to Account. Once you're in there, Connect with Facebook or ATA.
Now go to the device that you wan the account to be transferred to. If it already has an account, then go to accounts in settings, and scroll down to disconnect your device. Now, it will take you to the screen to create a new account. Select the option where it says "already have an account?". From there, log into it with the ATA or Facebook of the account you want on the device.
After(option), go back to the first device and open settings. Go in accounts and disconnect your account.
Please wall me if you get stuck or need more help.
