I do appreciate that the devil is always in the details, but I'll be straight that their new(?) "Upgrade insights" tab/api <https://docs.aws.amazon.com/eks/latest/userguide/cluster-insights.html https://docs.aws.amazon.com/eks/latest/userguide/cluster-ins...> goes a long way toward driving down the upgrade risk from a "well, what are we using that's going to get cut in the new version?"
We just rolled off of their extended version and it was about 19 minutes to upgrade the control plane, no downtime, and then varying between 10 minutes and over an hour to upgrade the vpc-cni add-on. It seemed just completely random, and without any cancel button. We also had to manually patch kube-proxy container version, which OT1H, they did document, but OTOH, well, I didn't put those DaemonSets on the Nodes so why do I suddenly have to manage its version? Weird
Touching CNI is always a potential downtime inducing event, but for the most part it was manageable
