I have my PvZ 2 account all across my devices, and that's really simple.

1) Make sure you have an iCloud account and it is logged in to both device.

2) On your iPad, select Settings > iCloud > Storage & Backup > Manage storage. Select your current device.

3) Make sure the PvZ 2 button is turned on.

4) Go back. There will be a "iCloud backup" button. Turn it on so you will not have to back up multiple times.

5) Press "Backup Now". Wait till it has finished.

Do this on your iPhone too, and you're good!
