Should I upgrade old machine to Big Sur before migrating to new M1 Silicon Mac

No need to do that.
I have a 2012 Catalina Mini and it migrated eventually into the new M1 Mini.
All my apps and files were successfully transferred - there were some "intel apps" that did not work but that's because the M1 is not Intel.....
Just a bit frustrating on the transfer I found - startup screen data transfer didn't work, wireless sees each other but no go, Migration Assistant with wired network - no go, and for me the only way it worked was a TB3-TB2 adapter w/ Thunderbolt cable to make the physical connection.\
You may want to be ready with a USB-C cable between your devices instead of relying on wireless or wired network transfer...

First... Are ALL your programs BigSur compatible? I have and use multiple programs that are not yet compatible with BigSur. This is not an issue if they will run under Rosetta2 or not on a M1 machine. They will not run under BigSur on an intel machine.
I have no idea... I have lots of third party apps. Is there a way to check before upgrading?
I've just been checking with the App developers to see if my Apps are. I don't know if there's a compatibility website somewhere that collates this kind of info. Carbon Copy Cloner recently said to hold off on upgrading to BigSur until they resolve some problems.
