So why the apple website support suggests WiFi by putting computers next to each other? I even called and they suggested WiFi. But I was not sure and therefore I came to the community. Thank you all for your help.
A few years ago I used the TM on some older iMacs, and it was a pain, for one reason, TM doesnt transfer serial numbers for some applications, so they needed to be reserialiazed, or reinstalled. I tried WiFi and it was sucesful transfer. But I heard that it might be an issues today. So according to rkaufmann87 and Kappy I will need an external clone HD, which I already created using Super Duper.
For some reason I thought connecting 2 computers direct is the fastest way, and more reliable. But since I have 2 version of thunderbolts I will have some issue, like buying some conversion wires.
