    I have a Mid 2012 iMac with Thunderbolt 2 and a new iMac with Thunderbolt 3.

    I want to transfer my data from one to the other using the Migration Assistant and started on 1GB Ethernet. The Transfer is now saying it will transfer in 18 hours and is going up.

    I swapped out the Ethernet cable with a Cross over cable and Directly connected them. It says it is transferring at 9MB/s When I started it was at over 60MB/s

    I was hoping to get a Thunderbolt 2 to Thunderbolt 3 Cable to use Migration Assistant at t he 20GB/s rate.

    Though all I can find is a Thunderbolt 3 Male to Thunderbolt 2 Female, so It would seem like I would also need a Thunderbolt 2 to Thunderbolt 2 Cable? Would that work?

    Why not use migration assistant via Time Machine backup?

    You need this: https://www.apple.com/shop/product/MMEL2AM/A/thunderbolt-3-usb-c-to-thunderbolt-2-adapter and then a regular Thunderbolt 2 cable.

    You would never see that speed as Sata 3 only has 6Gb/s of bandwidth. If you have a hardrive instead of an SSD that number would go down even more and would only be slightly faster that the Gb ethernet.
