How to transfer game progress from IPod to IPhone?

I have a 32GB ipod 4 and got a 8GB iphone. Im wondering how I can get the app progress (level, stages) from ipod to iphone.

Looking for step by step of how to do this.

You cant. I did extensive internet research on the topic and it cannot be done. I really want to transfer my minecraft pocket edition world to my new ipod but it wont work. Sorry bub
