2 • Upgrade CN2 software by applying updated manifests. • Uninstall CN2 by deleting Contrail namespaces and resources (where supported). More than a CNI plug-in, CN2 is a networking platform that provides Install CN2 on the central cluster. a. Apply the central cluster manifest. This manifest creates the namespaces and other resources required by the central cluster. It also creates the contrail-k8s-deployer resources in namespaces other than those listed above. To uninstall Contrail Analytics, see the Install Contrail Analytics and the CN2 Web UI section. 4. Delete any other resources and namespaces (for example
