I do not know of any standard options that could do that. The following may work for you though:
- Check Superuser or Google for how to do each of the following:
- Put the old hard drive with the data to be migrated into the new
box, completely replacing the new harddrive with the old one.
- Perform a repair install ("refresh your PC") on the old windows, inside the new box.
- Clone the old harddisk to the new one and swap them back
If you want to continue using the old box as well, you need to create (and restore afterward) a complete image backup of the old harddrive.
The "repair" install will keep any files, accounts, settings and store apps intact.
Installed software can not be kept. The "repair" will put a list of removed software on the desktop so you can easily identify what to reinstall.
I have not tried this exact procedure, but I have exprience with similar hacks. Windows 8 usually recovers quite well from these shenanigans.
