Adding data centers to an existing two-data center setup

If you have an existing two-data center setup for Global Mailbox, you can add more data centers by following certain steps. The steps include setting up a shared file system, installing Cassandra nodes, joining the Cassandra nodes to the existing Cassandra cluster, installing ZooKeeper and Watchdog, joining the ZooKeeper and Watchdog nodes to the existing nodes, updating the global.properties file, and finally, installing IBM® WebSphere® MQ, Sterling B2B Integration, and Global Mailbox.
