So first, apologies for hijacking the thread, but this is a hot issue as we are planning 4.2.x to 5.x.y upgrade in the unspecified future, and are currently running CNFS and clustered CIFS. Those exporter nodes are in need of replacement, and I am unsure of the future status of CNFS and CIFS (are they even in 5.x?). Is there a way to roll out protocols while still offering CNFS/Clustered CIFS, and cut over when it's ready for prime time?
