Supported upgrade paths
NetBackup Flex Scale supports both rolling and parallel upgrade.
In a rolling upgrade, each node in the cluster is upgraded successively and restarted without shutting down the cluster. During a rolling upgrade, cluster services are not available for a very limited period. The nodes restart automatically as part of the upgrade process. Rolling upgrade minimizes the service and application downtime by limiting the downtime to the time it takes to stop and restart the NetBackup services on the cluster nodes.
In a parallel upgrade, all the nodes in the cluster are upgraded and restarted simultaneously and the services downtime is part of the overall upgrade duration. During a parallel upgrade, cluster services are not available after the cluster nodes are restarted. The nodes restart automatically as part of the upgrade process.
The following upgrade paths are supported forNetBackup Flex Scale:
From version 3.2, and 3.2.100 to version 3.5
