One caveat - the NVX devices will have to be in the same major revision number as each other for the streams to work.? An encoder on 2.x.x can't steam to a decoder on 5.x.x and so forth.
?
And once an NVX is updated to 5.x or beyond, rolling back the firmware to earlier than 5 will brick it.? Learned that the hard way.
?
Best to just go ahead and get everything on 7 right out of the gate.
