Hi there Robert and welcome
This is all automatic. When you first turn on a new Kindle, it will step you through the process to register it.
Make sure you first connect it to your wifi network, then register it with the same Amazon account you used on your Kindle 2
Once done, all your books will then be available on this new Kindle to access as they are all linked to your account (not to the actual Kindle)
If you would like any additional information or assistance, please do not hesitate to let me know.
Else if you can take a second to rate my service by clicking one of the stars at the top of the screen then submit, that would be greatly appreciated.
