I'm looking for a solution to upgrade 350 computers currently running Windows 11 Pro to Windows 11 Enterprise. We have a site license for Windows 10 Enterprise, and my predecessor opted for Windows 11 Pro instead of upgrading directly to Enterprise. I attempted to use the Windows 10 Enterprise key, but it didn't work. While I can manually install Windows 10 Enterprise and then upgrade to 11 Enterprise through WSUS, I'd like to avoid doing this for all computers if possible. I don't have Intune, and we're currently on E1 in O365. Any advice would be greatly appreciated!

Have you tried entering the product key using the slmgr commands? I had a similar situation before where I used `slmgr /ipk` followed by `slmgr /ato` to activate the upgrade. Just a heads up, since you don’t have a KMS server, it might not work the same way for you, but it’s worth a shot!

I tried putting the key in the update product key section, but it didn’t update the OS. I did use the slmgr commands as well, but with no luck.
