Because I am changing the OS from OEM to Retail, only way is to remove the OEM version and fresh install a Retail version with a valid key. I think this is the correct way.
No. You can change from OEM to Retail by just going to Activation under settings and enter the new product key. But there really is no need to change from OEM to Retail on one that is already installed and activated.
Going from Home to Pro you just need to run the Windows Pro setup.exe just like you would upgrading any Windows to Windows 10 Pro - when it asks you for a Product Key, you enter your purchased Windows 10 Pro key. It will upgrade to Pro, not clean install that way.
Look in Settings - System - About. Right there is the link to "change product key or upgrade your edition of Windows". That is where you would enter your Pro Retail Product Key to initiate the upgrade. See here:

I'll probably just get another OEM key then. I was just hoping I wouldn't have to see one of my keys go unused because we're retiring one of the machines but I see what they are doing.
Thanks for the help, guys. Appreciate it. :)
