Couldn't you take the hard drive out of the side of the old one, and put it into your new one, then save it to an external hard drive or flash drive, put the new one back in? Or I guess if the old HD is bigger, you could leave it in the new one, but shouldn't that work? I have an old fat PS3 and only a few of my friends have the skinny ones, so I'm not 100% sure that they are removable, but swapping a hard drive is easier than starting fresh.
