This migration procedure applies only to distributed 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 OAM configuration mode, without an interruption in service. 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), you must change to NWDL licensing to operate in OAM configuration mode. The following migration procedure includes an overview of the process required to change to NWDL, however, consult with your Ribbon representative to ensure you are prepared to complete this step before starting migration procedures.
Check the SBC cluster configuration status on the EMS before beginning migration to ensure all pending changes are saved back to the EMS. The status should not be "Edit Configuration," which indicates some changes still must be saved and applied.
Click the radio button adjacent to the name of the cluster you are migrating. The Details tab for the selected cluster opens by default.
