Configure the name server or name servers with the new zones to represent the new subdomain names created for the new subplexes.
You can use the same name server that was used for the sysplex zones, or another name server or name servers. These name servers must meet the existing requirements for ADNR, as specified in Step 3: Decide which name server or name servers are to be managed by ADNR. Configure any security requirements in the name server for the new zones, such as access control lists or shared keys. Delegate the new zones as child zones from their parent name servers.
If you are not planning to use the existing sysplex domain name, remove that zone from the name server configuration file on the primary and secondary name servers. Update the parent zone so that it no longer delegates to the zone that you are removing.
