samba - Nov 2020 - How to change gateway in local network after upgrade samba?

?Hello all;?I?need to clarify a few doubts regarding the samba4 update.
?I have a server with CentOS 7 operating system, with samba 4 version 4.11.4 as
AD DC. I want to update to samba 4.13.2. For this I will use another server with
CentOS 8 operating system.
?After installing samba 4.13.2 on the new CentOS 8 server, I must join it to the
domain I have at the moment, then transfer the FSMO roles and then demote the
server with samba 4.11.4
?My question is the following:
The entire local network has as a gateway the IP address of the samba 4.11.4
server, of course the new server with CentOS 8 and samba 4.13.2 operating system
will have another IP address.?How do avoid having to change the gateway address
on the entire local network?
?What is the best way to do that?Rommel Rodriguez Toiracrommelrt at nauta.cu
