[Samba] Remove samba4 server from Domain

[Caleb O'Connell]

I initially setup a samba4 domain with three servers.  The first server I 
setup was of course the SOA server for the DNS.  I need to now remove this 
server from the group and pass along it's roles to another server.  I 
updated the operations master to the new server but aside from that I Cannot 
get the Microsoft tool to change the SOA record.  

Basically, I need to know what steps need to be gone through to change all 
the primary functions of an AD domain from one samba4 server to another.  

I searched Google and checked all the options I could find in the samba-tool 
utility but I can't seem to find where this would be done.

Any help, suggestions or links to existing documentation would be great.

Thanks in Advance
