I saw that earlier ....... and it made me nervous. I'm not a very tech savvy person. So, even the simple tasks for others appears daunting to this old codger. I've heard the PSN Cloud approach is easier - and was wondering if anyone else had used it.
I've done it a while back. I did not have to do the ethernet cable transfer thing either. If memory serves me right, these are all the steps i did and it worked. Give this a shot if you'd like.
1. Save game data to memory stick (So you'll have a backup if cloud fails), disconnect old ps3
2. On new ps3, setup your internet connection
3. Sign in on psn using existing account (the one that has all your gt6 data)
4. Check for software updates in xmb menu and update system if needed.
5. While still signed in on psn, load gt6 and install all in game updates.
-Cloud should have everything restored for you at this point.
BUT:
- If game is asking to start new career, quit game, plug in memory stick and copy game data to ps3. Make sure you're still signed in... Start game and you should have everything there (credits, cars, progress, etc).
Let me know if it works, good luck.
