- If upgrading Cluster Federation components from 1.3.x, the `federation-apiserver` and `federation-controller-manager` binaries have been folded into `hyperkube`.  Please switch to using that instead.  (#29929, @madhusudancs)

Please consult the installation procedure you are using (kargo, kops, kube-up,
kube-aws, kubeadm etc) for specific advice.

1.6 encourages etcd3, and switching from etcd2 to etcd3 involves a full
migration of data between different storage engines.  You must stop the API
from writing to etcd during an etcd2 -> etcd3 migration.  HA installations cannot
be migrated at the current time using the official Kubernetes procedure.
