This is something I'm trying to simplify with my product. The foundational security features of U2F (you can't interrogate the device to find out what other services are set up) make it basically impossible to migrate them to new devices, but all the other capabilities of the Yubikeys can be moved across.

This is really why U2F falls over in the Enterprise, at least from what I've seen. Customers want centralised management, but the U2F protocol just can't support that.
