Iam trying to transfer a Valid Rocket from a Mag54 over to a T2. I Go to the Check your Rocket Screen a d chnage the MAC address on the Mag 54 back to Zeros, and hit apply, It comes up saying the MAC Address already Exists. How do i Transfer the Rocket from the Mag54 over to the T2

dont change to zero and hit apply. delete existing Mac and enter T2's Mac which labeled as ID and starts with 00:1A;79....then apply.
