Anything you have purchased through Amazon will be linked to your account and will automatically be available when you register your new device. Everything else can be transferred by connecting the old Kindle to a computer using the USB cable and then copying items to your the computer. Disconnect the old Kindle and connect the new one. Now transfer the files from the computer to the new Kindle. Anything purchased can be transferred this way, but will not work if the two devices are registered to different accounts.
