To upgrade StarWind Virtual SAN to a newer version, a specific upgrade sequence and procedure must be followed to avoid service disruption.
StarWind Virtual SAN is a VM storage solution mirrored between configured cluster nodes and treated just as local storage by both hypervisors and clustered applications eliminating any need in physical shared storage.
