I recently had the same problem. Wife had an iPod touch and now has a iPhone. She wanted a team lava game transferred. Looked online and came across iexplorer. I read you just copy all the contents in the folder of the app and just paste it on the new device. Didn't work and later found out that teamlava saves the data on their end. You provide the info they need and they will make the switch. Look up Iexplorer, might work for you.
