I am retiring an old computer which is currently running an activated copy of Windows 11 Pro, non-OEM. I am replacing it with a newer machine that has already been activated with a Windows 11 Home digital license.

I wiped the drive and did a fresh install of Windows 11 on the newer machine using a Windows 10 Pro activation key. The install would not activate, saying that the machine had previously been activated with Windows 11 Home. It would not let me use the Windows 10 Pro key to upgrade my Window 11 Home to Pro.

I wiped the drive again and installed Windows 11 again, this time not specifying any key. Windows 11 Home ended up being installed and activated.

Besides purchasing a completely new Windows 11 Pro key, is there any way I can upgrade this machine from Windows 11 Home to 11 Pro using a Windows 7 Pro or Windows 10 Pro key?

All I really want is the ability to use RDP to manage this newer machine.

The key should have worked. Not knowing the answer to why, I have to ask, how did you try to enter the Pro key?

The Windows 10 Pro key was entered during the first installation.

During the second installation I entered the Windows 10 Pro key in Settings->System->Activation->Change Product Key

So if you go to System > Activation > Change product key, it will not accept the Windows 10 Pro key?

I'm not sure if you can use a generic pro key first, then enter the genuine one?

Windows 11 only accepts Windows 10/11 keys, it no longer accepts older ones.

That's how I tried to enter my Windows 10 Pro key. It's possible that I could have made a typing error, but then it should have complained that it was incorrect, not that the machine was already activated.

It's possible that it won't accept the Windows 10 Pro key because it was used on a different machine, but I'm retiring that computer and want to reuse the key on the new computer.

Not the end of the world, but I'll try again later.

Have a look here: Generic Product Keys to Install or Upgrade Windows 11 Editions Tutorial

Maybe you can try this key first: VK7JG-NPHTM-C97JM-9MPGT-3V66T

If the PC has an existing digital licence for Pro and you are connected to the internet when you install the generic Pro key, then it will upgrade to Pro and be activated. No need to add any other key later.

If it doesn't have a Pro digital licence it will tell you so and not let you upgrade. You could disconnect from the internet and change to the generic Pro key. That will let you upgrade, but it won't be activated. You'd then need a valid Win10/11 key to activate it.
