Windows 10: Transfer Win10 HOME Key retail to another PC after upgrading to PRO retail

As the subject line states...


I have 2 PCs. One with a HOME retail key and one with no key but is an older PC ... let say it currently has no OS. I want to upgrade this newer PC from HOME retail to PRO retail. I have already retrieved the HOME key and saved into a text file. From my understanding, I go into System -> Change key and can put in the new PRO retail key to upgrade from HOME to PRO.


Once I do that... can I now use the HOME retail key on the older PC? Again... I keep stressing retail in this email because I fully understand that OEM keys / upgrades are retained for the PC they came installed on and are not transferable. However, both my HOME and PRO version are retail keys.


If the answer is YES ... please don't just say YES. Please provide the steps necessary to transfer the HOME key so I don't lose it accidentally.


Thanks.

Can I upgrade OEM Win10 Home to Retail Win10 Pro?

Moving to a new PC that I'm building myself. Currently running Dell OEM Win10 Home. New PC will have Win10 Pro, MSDN (multi-activation or retail keys) version.

My backup software can do a "system transfer" that will allow me to transfer everything (OS and applications) to the new computer.

Should I upgrade from OEM Home to MSDN Pro on the old computer and then transfer everything to the new computer?

Or just install Win10 PRO MSDN on the new computer and use the backup software vendor's application transfer program to move the applications and registry entries.

My goals are:

1. Not have any "dinosaur bones" either from the OS on my SSD from the old OEM Home version on the new PRO version
2. Not have to reinstall and reconfigure everything (which would take about a week)

Thanks for any advice I can get...

Are Windows Retail Version Upgrading to Win 10 OEM??

Nah, couldn't post until I had written confirmation.

Update:
I am currently in the process of doing a clean install with a newly generated Win10 Pro product key that Microsoft have just emailed me. I now have two licenses of Win10 for only the single purchase of Win8.1 retail!!! Well done Microsoft for listening!

• License 1 = Win8.1 Pro Retail + Free promotional Win10 upgrade = Win10 Pro with full transfer rights until July 29 2016. On that day the license will be identified by Microsoft as preinstalled. You would now have a Win10 Pro licensed device, tied to the hardware for the lifetime of the device.
• License 2 = Full standalone Win10 Pro license = Standalone Win10 Pro with permanent full transfer rights.
