Use the Optimal Service Upgrade feature to upgrade a Security Gateway or VSX cluster from R75.40VS to R80.10 and future major releases. This feature upgrades the cluster with a minimum loss of connectivity.
When you upgrade the cluster, two cluster members are used to process the network traffic. New connections that are opened during the upgrade procedure are maintained after the upgrade is finished. Connections that were opened on the old version are discarded after the upgrade.
You can also use the Optimal Service Upgrade feature to upgrade a VSX cluster from R67.10 to R80.10. When you use this feature to upgrade from VSX R67.10, download the R67.10 upgrade Hotfix and install it on one VSX cluster member. For more about upgrading to R67.10, see the R67.10 Release Notes.
For more about the Optimal Service Upgrade and to download the R67.10 upgrade Hotfix, go to sk74300.
