Catalina TM Backup to New Mac mini running Big Sur

Should I use a Catalina Time Machine backup (from MBP) to Migrate data to a Mac Mini(M1) running Big Sur OR should I upgrade MBP to Big Sur and make a new Time machine back up then migrate data to Mac mini?

MacBook Pro 15″, macOS 10.15

You can do either. Time Machine can be connected to the M1 during setup.


I did a migration using Migration Assistant from a Catalina Mac to the Big Sur using a Thunderbolt cable.


Wireless did not work for the M1 data migration.
