Now that CentOS 7.5 ships with Samba 4.7 and has MIT Kerberos support, I would like to migrate away from the Sernet packages. Currently I have two Samba4 DC's. Can I easily swap the packages? Do I need to move all roles from #1 to #2, demote/unjoin, swap packages, rejoin/promote? .. What's the right way to migrate? Thanks in advance! j
