i had an old iPod which broke, making me lose my old graal account so i bought a new ipod. my current ipod has a farely acceptable stats (for me) and i recently fixed my old ipod, my new account is VIP and my old one is not. if i transfered my stats from my old iPod to my current account would it just add them or would it erase and re write with my old accounts stats?  

It would delete your old account and add everything to your VIP. If you already got items on the VIP account which are also on the old account, you will keep them on the old one.
