    Hello

    was your key purchased from Microsoft?

    on the install if it prompts for key select I don’t have product key to continue install.

    when install is done sign in with the Microsoft account you used for the license purchase. go to Settings > System > Activation, run the troubleshooter, choose the hardware change option. When it asks you where it is installed on right now, you should choose the old device name. Then click on Activate button. And on the next screen when it asks you where to transfer it to, choose your new device name. See if that does the trick.
