Using a 2016 server will not work. As I said, you would first have to
classicupgrade the NT4-style domain, then join a 2008 server to it
(using a 2012 server is experimental). Now demote the Samba DC and
start the upgrade climb, how you do it is up to you and what is
possible ;-)

OR, as I also said:

Probably easier to set up a new domain ;-)
