By default, when a Tanzu Kubernetes Grid cluster is upgraded, the nodes are upgraded one a time. In my labs, I usually only have a single control plane node and at most two worker nodes since they are very resource constrained and not running any kind of demanding workloads so this isn’t a concern I …
