Transferring game saves from one account (or profile) to another is not impossible; once you save a game on one profile, you can give the save to a different one. This is useful if you decide to start playing under a different profile in the future or if you played the game on the wrong profile to start. The Sony PS3 makes the transfer a painless process.
Power on your PS3 system and one controller.
Log into the account that has the game saves.
Select “Game” from the home screen.
Open “Saved Data Utility.”
Highlight a game save that you want to transfer and press the triangle button on your controller.
Choose the profile that you want to transfer the save to.
