How long does it take to transfer the files? My computer has been doing this for 12 hours already, and still not finished. It's been showing for 11 hours "About 25 minutes remaining". What should I do?

Probably the migration is stuck. If you have connected both computers using an Ethernet, Thunderbolt or FireWire cable, connect and disconnect it.
If you have connected them using Wi-Fi, restart the computer to what you are migrating the files and migrate the data again
