You can upgrade native and Tanzu Kubernetes Grid Service clusters by using the Kubernetes Container Clusters plug-in.
You can upgrade a native cluster, if your service provider created one or more Kubernetes templates with higher Kubernetes versions using the VMware Cloud Director Container Service Extension CLI.
For Tanzu Kubernetes Grid Service clusters, if the parent supervisor cluster supports a higher Kubernetes version, you can upgrade a Tanzu Kubernetes Grid Service cluster in VMware Cloud Director by using the Kubernetes Container Clusters plug-in.
