Check Tanzu Kubernetes Cluster Compatibility Before System Upgrade
Before upgrading the vSphere with Tanzu infrastructure, including the vCenter Server and the Supervisor Cluster, refer to the Knowledge Base article https://kb.vmware.com/s/article/82592 for guidance on how to check if any Tanzu Kubernetes clusters are incompatible with the upgrade. If a Tanzu Kubernetes cluster is incompatible with the target infrastructure, upgrade the cluster before proceeding with the system upgrade.
