Two servers (machines) in the same domain. 
 They both are Domain Controller.

 CentOS7 - samba 4.11.4  (hostname gtmad)
 CentOS8 - samba 4.14.3 (hostname gtmad1)

both compiled.

 The FSMO roles are in the server with CentOS8:

# samba-tool fsmo show
ldb_wrap open of secrets.ldb
SchemaMasterRole owner: CN=NTDS
Settings,CN=GTMAD1,CN=Servers,CN=Default-First-Site-Name,CN=Sites,CN=Configuration,DC=gtm,DC=onat,DC=gob,DC=cu

Then why does it matter if the ip and name changes ?

I would create a new DC by joining it to the domain, transfer all the
FSMO roles to it and then demote the existing DC's, adding any other 
new DC's required.
