The Multi-Version Cluster (MVC) mechanism lets you synchronize connections between cluster members that run different versions.
This lets you upgrade to a newer version without a loss in connectivity and lets you test the new version on some of the Cluster Members before you decide to upgrade the rest of the cluster members.
To everyone at Check Point who worked on this feature (Multi Version Cluster Upgrade). I have used this several times now when updgrading from R80.20 / R80.30 to R80.40. It works completely without any disruption.
