This migration procedure applies only to SBC SWe deployments in the OpenStack cloud environment that are instantiated using Heat templates.
Beginning with release 8.0, SBC clusters deployed in an OpenStack cloud must use either OAM node or Direct Single configuration management. For existing clusters that use the SBC HeadEnd configuration model, the following procedure outlines the steps to migrate the cluster and its current configuration to Direct Single mode. In this process, you duplicate the existing cluster to create a new cluster that holds the same configuration. You then instantiate new SBC nodes for the new cluster and delete the original cluster. Use the links provided with a step for more details on how to complete it.
If your deployment is not already configured for network-wide domain licensing (NWDL) and you plan to use it in your deployment, step 11 in the following procedure provides an overview of the process to change to NWDL. However, consult with your Ribbon representative to ensure you are prepared to complete this step before starting migration procedures.
Click the radio button adjacent to the name of the cluster you are migrating.
Click Duplicate Cluster. The New Cluster pane opens below.
Refer to Creating an SBC Cluster for information to specify other cluster options, then click Save. The duplicated SBC cluster inherits its initial SBC configuration from the duplicated cluster.
The remaining steps are service affecting and must only be performed during a maintenance window.
