## WARNING: etcd backup strongly recommended

Before updating to 1.6, you are strongly recommended to back up your etcd data.
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

Mientras esperas, vas con esa persona 😍 y eliges una mesa, se sientan y hablan durante un rato largo (ya que las hamburguesas son muy impresionantes y necesitan un rato para prepararse ✨🍔✨).
