When you install DCS management servers then it will either be the Primary or a tomcat only install. The "tomcat only" install sets a registry key that stops the install from modifying the database.
If you intend to make a new server the primary, you will need to set it's tomcat only registry key to false or delete TomcatOnlyInstall registry key on this primary chosen server and then set the TomcatOnlyInstall registry key to TRUE on the other DCS managers.

Here is the registry key and the value:
