Is Network Manager in 11.3 different from 11.2?

For many years I’ve used scpm to reconfigure my laptop bu changing the nfs
fstab file depending on what environment I was in. This year I understand
scpm is no longer available in 11.3, and I’ve been told to use network
manager. In 11.2 network manager, despite it’s name couldn’t manage
networks, just connections. Has network manager changes so I can easilily
alter my nfs setup as I move my laptop from connection to connection.
