[Success ] Big Sur Installation a Success, with zfs working

[z0lt4n]

But I will do a clean install with OC 0.6.3
Had to use gibMacOs, the download would not work.
A few screenshots
This ended in an error...

Download via gibMacOS & launch InstallAssistant.pkg

In the /Applications folder you can then find the installator, launch it to see if it works and then you can quit it. (Or continue if you have a good backup and OC 0.6.3)

Making installation media via command line :
sudo /Applications/Install\ macOS\ Big\ Sur.app/Contents/Resources/createinstallmedia --volume /Volumes/myVolume

The rest of the actions you can find here : https://dortania.github.io/OpenCore-Install-Guide/

Upgrade to OC 0.6.3 and to BigMacOSX° succeeded, but installing https://openzfsonosx.org/ was an utter failure => going back with restore from CCC
Conclusion:
Catalina is here to stay for a while…
But I had fun

Success! At last!
Steps

1. Full backup of my Catalina System with CCC
2. Boot in backup
   Export all of my zfs partitions
   Uninstall all of zfs, with the scripts provided in:
   /Volumes/OpenZFS\ on\ OS\ X\ 1.9.4/Docs\ \&\ Scripts/
   
   
   
   In that order : uninstall-openzfsonosx.sh, uninstall-make-install.sh & uninstall-complete.sh
   Just to be sure (was like blasting a bazooka at a mouse, but…)
3. Installed Big Sur and did a 'Migration Assistant" with my backup disk, without the zfs kernel extensions
4. Downloaded https://openzfsonosx.org/forum/download/file.php?id=215&sid=bb455208805ce22b6d6b0653e9c5e31d
   
   
   
   You will have to authorize the use of those kernel extensions in System Preferences > Security and Privacy > General
   
   
5. [Optional]
   Change your scripts where you invoke the zpool command
   Reason, the location of the executable is changed
   
   
   
   The former location was "/usr/local/bin/zpool"
   The one in Big Sur is "/usr/local/zfs/bin/zpool"

Hope this is of some help for one of you.
