Migration Assistant claims download source cannot be used because "may be damaged"

I am trying to transfer data from an iMac running OS 10.13.6 to a brand new iBook Air M3. Both are on the same wireless network, and sitting side-by-side. The Migration Assistant on the MacBook claims that "The selected source cannot be used for migration because the volume contains a macOS or OS X installation which may be damaged". However, I have just run Disk Utility First Aid on the iMac, which received a clean bill of health. How can I proceed?

Tried that. Whether the TM disk is first connected to the older iMac, or whether it is connected directly to the iBook by firewire, the result is the same - "The selected source cannot be used for migration".

Do you have a Time Machine backup of the old Mac? If so, try setting up the new one from that.

Personally, I always set up new Macs from a TM backup.

OK, the question of migration is now moot because by updating the machine to OS Sonoma, I seem to have lost administrator status - a major problem which overshadows migration issues...
