Hello @Anandu 

Configuration Description
Same AOS and hypervisor versions The node is added to the cluster without reimaging it.
Same hypervisor version but different AOS version The node is automatically reimaged before it is added. However, if the AOS version on the node is higher than the version on the cluster, you can upgrade the cluster to the higher version. If you do not upgrade the base cluster to match the node AOS version, the node is reimaged automatically to match the lower AOS version of the cluster. For more information about how to upgrade your cluster, see the Acropolis Upgrade Guide.

Hello @Anandu 

Discovery requires that IPv6 multicast packets are allowed through the physical switch. If you see a failure message, review the requirements in Prerequisites and Requirements.

So the recommended solution is upgrade the cluster and expand the cluster?

So should I connect all ports of nutanix to switch during initial configuration?
