Migration Assistant fails in Tahoe

I'm trying to use Migration Assistant to migrate from an M1 Mac Mini to an M4 Mac Mini, both running the latest Tahoe. I've tried it multiple ways, using Ethernet, Wi-Fi and a direct Thunderbolt connection. Each time, after I get to the part where a number is displayed on both computers, the "from" computer displays this message:


"Unable to use this machine for migration. A startup networking error occurred. Please restart this machine and try again later."


Does anyone have any suggestions on how to fix this?

Try from one of your backups....and compare your results(?)


The most trouble free way to move to a new machine, is using the Setup Assistant on the initial boot of a brand new machine— you have one shot here. Set up your MacBook Pro - Apple Support


The second best way is use the Migration Assistant.
