Win 10 Home to Pro upgrade

How do I upgrade from Win 10 Home to Win 10 Pro with a digital Licence. The in structions say

• If you have a digital license for Windows 10 Pro, and Windows 10 Home is currently activated on your device, select
  Go to Microsoft Store and you'll be prompted to upgrade to Windows 10 Pro for free.
  

Fine, but how do I get a digital Licence for Win 10 PRo??

Going to Microsoft Store via the upgrade with digital licence link, provides no opton for upgrading.

Any solution??

 

upgrade Win 7 Pro to Win 10 Pro

I have several times tried to upgrade my desktop (dual boot Win XP and Win 7 Pro) to Win 10 Pro using the downloaded ISO file, and keep my personal files and apps. It runs about 36 hours then fails. How can I make this upgrade? If not using the ISO file
is there another method to accomplish this ??

Thanks for suggestions.

 

Unable to upgrade to win 10 pro

I purchased win 10 pro from the MS store in Oct 2016. This downlaoded and upgraded ok. Recently the laptop died and has now been replaced. The new laptop came with win 10 home and has been activated. I now want to transferv my licence for pro to the new
laptop but I never received a key when I purchased it, it was a digital licence. But when I go to the MS store it does not allow me to upgrade. I am using the same MS account as I had used when I purchased pro. Any suggestions?

I spent several hours with tech support last night and wound up being updated to 1809, biut still only home not pro.
