Dosdude Patched Catalina to Monterey OCLP

I have a imac 12,2 with flashed k1100M looking to go from patched Success' href='/2020/12/install-macos-catalina-on-supported-pc.html'>Catalina to Monterey. Can I run the installer from my current OS and quit the installer to go to disk utility and format the drive to get a clean install or do I need to clean install High Sierra first? Also, will I be able to migrate my files from my current Time machine backup?
