Thank you. This early MacBook Air may have just a Thunderbolt 1. It is a very early 2014 model. I may pick up an adapter and see if it works, or I may have to do it through the wifi connection. Much slower for sure. The Apple Care tech person suggested the wifi approach, as they did not know of a Thunderbolt connector that would work. OK, I am confused. HA!
Given the cost of an Apple Thunderbolt 3-to-2 adapter ($50) and a Thunderbolt 2 cable ($30+) – hardware that you will likely never use again after the migration – it might make more sense to buy an external drive.
Unless you've installed an aftermarket upgrade, an Early 2014 MacBook Air would have, at most, a 512 GB SSD. So it wouldn't be hard to find an inexpensive portable hard drive or SSD large enough to hold a full backup, and provided that you got a large enough drive, it might be useful for backing up the new Mac after the migration.
