Question about Transferring Shows

I just ordered 2 Roamio Plus's to Replace my Series 3 HD and Premier. I know that on those units, you can transfer shows back and forth if the show permits it. My Question, how does the Roamio Plus handle that? Does it do the same? and also, can you Stream from one Tivo to the other instead of having to transfer? I know that the Mini Streams.. Just not sure how it works between 2 Roamio Tivo's



Thanks, Connor
