Data Transfer Utility
1. Connect both PS3 (A) and PS3 (B) with a LAN cable and connect both PS3 to the TV (using different video input connectors). (Please note, do not unplug any cables when the PS3 power is on.) Turn both the current PS3 (A) and new PS3 (B) on. Please note, firmware (v3.15) must be installed on both systems.
2. On the XMB of PS3 (A), scroll to the Settings category and select [System Settings] and then [Data Transfer Utility]
3. Follow the instructions on-screen and select [1. Transfer data from this system to the other PS3 system.]
4. When PS3 (A) is in standby and ready for transferring data, switch the screen to PS3 (B), scroll to the Settings category on XMB and select [System Settings] and then [Data Transfer Utility]
5. Follow the instructions on-screen and select [2. Transfer from the other PS3 system to this system.]
6. After transferring the data, follow the instructions on-screen.
7. If content that was downloaded from PlayStation Store was transferred as part of this operation, you must activate PS3 (B) before you can use the data. Log in to the PS3 system as the user who owns the content, and then select (PlayStation Network) > (Account Management) > (System Activation) to activate the system.
No, it just doesn't work on rebug cfw. You need to go to ofw or another cfw to transfer.
