Notes:
• This task is only applicable in a cluster environment.
• This task upgrades the cluster to a new protocol version while the
cluster remains accessible.
• All nodes in the cluster must be upgraded to the new version of the
software before the cluster is upgraded. To avoid shutting down the
cluster, you must stop, upgrade, and restart one node in the cluster at
a time.
• Once the cluster is upgraded, it cannot be downgraded to the previous
version.
