Windows 10: Question regarding upgrade from Win 10 Home to Win 10 Pro

Hello. I am thinking of upgrading from Windows 10 Home to Windows 10 Pro. If I purchase the new product key, do I have to do a full backup of my computer as if for a full upgrade or does the new product key just unlock the upgraded version?

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??

 

DOWNGRADE TO WIN 7 ULTIMATE and UPGRADE TO WIN 10 PRO

I refer to the following Microsoft Community Team’s query:

“……Remember that question you asked on
Microsoft Community a few days ago?

The issue “DOWNGRADE TO WIN 7 ULTIMATE and UPGRADE TO WIN 10 PRO” is unanswered. The suggestion to refer to the link

https://www.microsoft.com/en-us/windows/windows-10-specifications does not answer my query as well. I knew the prerequisites of upgrading to Win 10 from either Win 7 Ultimate or Win 8.1 Home as I have read the min. requirements/machine
specifications to upgrade directly either from the aforesaid OSes beforehand. The issue is whether from Win 8.1 Home downgrade to Win 7 Ultimate and from thereafter upgrade to Win 10 Pro possible without technicality issues. Nevertheless, since I cannot wait
for either a reply to the abovementioned issue (or my reservation to upgrade from Win 8.1 Home), I then gathered/downloaded bits and pieces of probable drivers for my machine, formatted my HDD (1TB) for more than 18 hours, clean install Win 7 Ultimate SP1,
activated using my previously purchased license and ran Windows afterwards, ran updates until repetitive error (around 25 KB updates failed to install many times) popped up during tiresome cyclic updates process. Fed-up with the errors after failed tries to
source answers from Microsoft Community, I tried my luck by upgrading to Win 10 Pro. After couple of days, viola, I have upgraded to Win 10 Pro finally, whew! Now I am running this machine with Win 10 Pro for a couple of days now, being up to date and running
very well. Hopefully no problem/s will arise.

Thank to those suggestions though.

 

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.
