Open the config.plist with OpenCore Configurator.
Copy/Paste your current Serial, Board Serial, and UUID to the new config.plist.

Boot from the USB flash drive to make sure everything is working as it should.
Copy the new EFI folder to the EFI partition of your boot drive.
Update to Ventura as you would on a real Mac.
Hi, followed your instructions. I keep getting:
OCB: StartImage Failed - Already started
Halting on Critical error
