Is it possible to transfer save data from one specific account to a new ps3?

I would like to transfer just some of the save data from an old ps3 to a new one. My brother has got a new ps3, and he would like to transfer his save data to the new ps3, but i want to keep my save data on the old ps3. What do i need to do?Is it possible to transfer save data from one specific account to a new ps3?
All you need is a usb flashdrive. Go to 'Saved Data Utility (PS3)' select the game data you want, push triangle, then copy, and copy it onto the flashdrive. Then add it to the other PS3's Saved Game Utility. Simple.

EDIT: His PSN account is stored on a server so on his new ps3 user account he just has to sign-UP to PSN using the 'Use an Existing Account' option.
