The method that worked fine for me was using mbuffer. (I couldn't make 
netcat work, shame on me, but I also remember that there were several 
pros of using mbuffer. I think one of them was the ability to use digest 
to secure the transfer.)

See:

That being said, it's exactly two years when I last did a migration with 
zfs send | zfs receive. I hope that still works.

BR,
