Is it possible to transfer the save data of COD BO2 from a PS3 to an Xbox One S?
I'm planning to buy an Xbox One S and continue playing Black Ops 2, but I don't know how to transfer my save data from my PS3 to an Xbox One S.
No, unfortunately saves are formatted for the console on which they are created. Microsoft and Sony use completely different formats. It is not possible to move a save between console lines.
