Cross-Host Upgrade Guidelines

If the new Universal Messaging server instance is on different machine from the old instance, follow the steps below:

1. Go to the new_installation_directory/Universal Messaging/server/instance_name/bin directory of the instance and create a file named remote_realms_bootstrap.conf. Add a cross-host mapping property to the file using the format instance_name.address=new_host_name_or_IP_address (for example, umserver1.address=myUM1.com or umserver2.address=192.168.0.1).
2. Start the Universal Messaging server instance. The remote_realms_bootstrap.conf file will be renamed remote_realms_bootstrap_old.conf. When a source Universal Messaging server instance is bound to a specific network interface (absolute IP address), the interface of the migrated instance address will bind to 0.0.0.0 (all known interfaces on the port).
3. Open Enterprise Manager and make sure the Universal Messaging server instance is running correctly.
