We're excited to announce that we've fully migrated the Xbox Forums to their new home, here on the Microsoft Community forums!
As of today, going to forums.xbox.com will redirect you here to the Xbox area of the Community forums. We've moved all of your existing threads over so you can continue and start conversations with the new forums experience.
We sincerely appreciate the feedback you have provided over this transition and can't wait for you to check out the new Xbox Forums!
Your saves should be backed up on the cloud although I can't remember if it automatically downloads them to your new console or if it does it when you load each game up as it was back in December when I replaced my console.
Your personal data is linked to your gamertag so when you recover your profile onto your new console you should have everything back on there.
The only thing you will have to do again will be re-download/install games that you have purchased from the games store or reinstall disc based games.
