When your vCenter Server is converted to vSphere+ subscription, all license information is replaced with subscription information. For vSAN+ clusters, license information is replaced with subscription information.
If you have other VMware products with assigned licenses in your vCenter Server on subscription, you can view and manage their licenses in the vSphere Client. For example, if you want to turn a vSphere cluster to a Supervisor Cluster for running Kubernetes workloads, you can assign a Tanzu edition license by using the vSphere Client. See Licensing for vSphere with Tanzu.
