Upgrading to Windows 11 from 10 BootCamp on MacBookPro11,5

[KingCornWallis]

I am wondering if there is an in-place upgrade option that does not involve wiping my existing windows 10 installation to upgrade to 11. I originally installed Windows 10 via BootCamp (UEFI) and installed OpenCore after the fact.

Currently dual booting Sonoma and Windows 10.

Here is what I did to upgrade on mac mini 2014 -

Use rufus to create the windows 11 install usb that bypasses all windows 11 requirements (tpm etc.) Make sure it is the same language as your win 10 install or it can't do the upgrade. I accidentally selected English international rather than US and had to redo the installer.

Then run setup.exe from it, and you should be able to perform the upgrade.
Not sure if open core will make this problematic ?, as I haven't used it.
