New Mobo = new device.
If you have a Retail license, no problem
It will take a bit of planning.
After a few months or even a month before the offer expires, make a complete back up of your machine.
Updrate to Win10
Create or download the ISO media
Build the new machine and install from the ISO - a retail license can be transferred, an OEM cannot be transferred.
This might require phone activation
Now that I wrote that, I wonder how the "life of the device" plays into this.
Worst case is that you'll have to purchase a retail license at that time to remain legit. But that also means that you can keep the free upgraded version on the older machine.
