The new Xbox 360 Hard Drive Transfer Cable for Xbox 360 can be purchased online or from a local game retailer.

If you've purchased a new Xbox 360 console, you can transfer everything (games, videos, music, saved games, gamertags, and even your hard-won achievements) to your new console!

Two options are available for moving your precious information. You can either use the Xbox 360 Hard Drive Transfer Cable to move everything to your new console, or you can connect a USB flash drive if you have only a small amount of content such as your gamertag and saved games.

To transfer content to your new console, you need the Hard Drive Transfer Cable and the latest console software. To get the latest console software, sign in to Xbox LIVE on your new console. If your console needs new software, you'll be prompted to install it. If your console is not connected to Xbox LIVE, you can use your computer to download the console update from the Internet. Here's how: Get a Dashboard update.

Once you have the Hard Drive Transfer Cable, you're ready to transfer content.
