While attempting to upgrade from v4.7.1 to v5.x.x, the pre-upgrade fails with the following error: "Cluster name must be in FQDN format."
Is there a way to upgrade the name from "CLUSTER" to "CLUSTER.domain.com" without downtime?
Or, alternatively, is there a way to perform the upgrade without making this change/ingoring this message?
Interesting question @Coleman - let me see if I can find out.

Under the gear icon, can you select Join Cluster and Hosts to the Domain? If so, please follow the dialogs to join it to a domain.
If not here is the Nutanix portal URL on how to update the cluster name.
