Before starting the procedure, ensure that you go through the following points:
Ensure that the new server that you are adding to the zone meets all the requirements. For more information, see ZENworks System Requirements in the ZENworks Documentation site.
Ensure that the first Primary Server is at ZENworks 23.4. If the first Primary Server is at a lesser version, then installation might fail.
The first Primary Server should be up and running.
If you are using an external database, then ensure that the database is up and running.
If your ZENworks Management Zone is using the internal ZENworks Certificate Authority (CA), the new Primary Server is automatically issued a server certificate during installation.
If your zone is using an external CA, you must provide the new Primary Server with a valid certificate issued from the external CA.
Ensure that you have taken a reliable backup of the Primary Server.
