You have to enable multi-master publication before the first start of the Content Management Server. To do so, you have to configure the following property of your Content Management Server.

cap.server.multipleLiveServers=true

Caution

It is not possible to switch from an existing single-master system to a multi-master system by simply setting cap.server.multipleLiveServers=true. Please read Section 3.10.4, “Migrate to Multi-Master Management Extension” for a detailed description of the migration process.
