migration Assistant won't transfer data between mid-2012 MacBook air running catalina and 2019 MacBook air
I replaced my wife's mid-2012 MacBook Air with a 2019 MacBook Air. Both are running Catalina and there are no additional system upgrades available. When trying to use Migration Assistant, the 2019 can see the 2012 as a source in Migration Assistant. However, there is the yellow triangle with exclamation point. It says it can not be used as a source. "Ineligible - OS X upgrade required".
Can I get around this? Can I link in Target mode? Ports on each computer don't match to get a cable. Any help?
Thanks.
MacBook Air
