@ngc7789 : I also did the fresh install and migration assistant. I just seemed easier this way rather than to learn how to use CCC to make a bootable clone of Big sur/Monterey (although that's something I need to do...). I had the cloner strategy down as plan B in case the fresh install didn't work properly.
The only thing that didn't migrate properly were the folder icons for the Adobe Creative Cloud suite. If you have these applications, they reside in your Applications folder, and they custom folder icons that have "Ps" "LrC" "Ai" etc, in special colors. After the migration, they were there, but in generic folder icons. Functionally, the programs all worked, but it bugged me.
I simply uninstalled then reinstalled the applications.
