Will I lose my content?
If I trade in my old console, will I lose all of the content on my hard-drive?Quite simply, the answer is yes. None of the above retailers will let you stand in store and use the existing transfer cable to bring your games over from one hard drive to the other before you part with your old console. If you know someone in store you might be in luck, but otherwise you've lost all of your saved games. Don't worry about demos and arcade games, you can download these again if you transfer your account across to your new Xbox 360.
The only way round getting all your game saves across is to buy the new console, bring it home, do the transfer and then sell your old one privately or trade it in at your local store, keeping the credit to buy some games.
However, a word of warning. There isn't a cable that currently allows you to transfer data between the 20GB and 60GB premium. You'll only be able to use the official Microsoft cable to transfer between the 20GB and 120GB Elite.
The only other option you have is to invest in a memory unit and then copy your saved games to it before you trade it in. A 512MB unit currently costs approximately £29.99
How do I transfer my gamertag
Once you get your new console you'll no doubt want to get your gamertag back. It couldn't be simpler. You boot up the dashboard and click on 'Join Xbox live'. From here you can choose to retrieve and account. You'll be asked to enter the username and password that you chose when you set up your gamertag. Your Gamertag and points will be added to your new Xbox 360.
