### NOTE: This playbook cannot be used to deploy any new nodes to the cluster.
### Additional information:
### * Will not upgrade etcd
### * Will not upgrade network plugins
### * Will not upgrade Docker
### * Currently does not support Vault deployment.
###
### In most cases, you probably want to use upgrade-cluster.yml playbook and
### not this one.
