In the XMB go to game -> trophy collection and push triangle on your controller.
The menu will open and you’re free to select sync with server.
Next you should deactivate your system.
Next go to the parameters menu and check for updates.
Now to avoid errors during the transfer, scroll down to online grid connections and disable media server connection.
Then disable internet connection.
Finally scroll up in the system menu to the data transfer utility.
At this point you should connect your old and new PlayStation 3 together with an ethernet cable.
Note: it’s possible for you to use either a crossover ethernet cable or a standard patch cable.
The PS3 will be able to internally switch to know which cable you used.
Select transfer data from this system to the other PS3 system in the next step.
Click OK on the next screen after you have connected the new system with an ethernet cable.
This time grab the option to transfer data from the other PS3 system to this one.
Once the system connects it will ask you to format the new system which will erase all data.
Only do this if you are sure that you don’t have any information stored on the new system.
Note: The old system will not be erased during this process.
Note: Depending on how much information you had on the old system this may take quite a while.
I had about 35 GB of information on my PS3 and the process took about 40 minutes.
Select what method you want to use to format the PS3 with.
Unless there is something really personal on the system a quick format should be good enough.
The format will go really fast and then ask you to kickstart your PS3.
After it has finished it will walk you through the initial setup of the system.
