About this task

You can now automatically migrate Universal Messaging clusters using Command Central composite templates. Use Command Central composite templates to migrate all the Universal Messaging server instances that are part of the cluster, and add the following property to resolve the cluster node connections successfully after migration:

Procedure

Add the following property to the um-cluster section of the composite template YAML file present in the following directory: <InstallDir>/profiles/CCE/data/templates/composite : 
  <ClusterSettings>
           ...
             <ExtendedProperties>
                <Property name="migrationType">SAME_HOST or CROSS_HOST</Property> 
            </ExtendedProperties>
        </ClusterSettings>
Note: A Universal Messaging server instance mapping file called remote_realms_bootstrap.conf containing information about the new Universal Messaging hosts is automatically generated in each of the Universal Messaging server instances. The mapping file is used to identify the new hosts, and to form the new cluster.
