Windows 10: Moving my Retail Win10 to a new PC

Hi all,I have a retail version of Win10 on my current 10-year old PC and have located the partial product key and other details found via the command prompt. I'm ordering a new custom PC and obviously want to transfer my Win10 across. After a quick online search, the deactivation process seems very straightforward. However, I'm a little uncertain about the steps for reactivation on the new PC, which will NOT have an OS when purchased.Is it enough that I have the details above, or do I also need Win10 saved to a USB the new PC won't have a CD/DVD/Optical drive? If so, how do I get this onto t

Transferring Win10 retail to new PC

I plan on buying a retail copy of Win10 before the new year but I also plan to build a new PC before the end of 2020. The copy I'm looking at says retail 1PC and I'm pretty sure it just means one at a time. Just want to be sure that when I build my new
PC I can still decommission old PC and install on new build.

 

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...
