Automated Zero-Downtime Platform Upgrade Process

NetBrain platform upgrades currently require a single upgrade execution path that can result in service downtime while components are brought offline and updated. Achieving zero downtime today requires customers to manually perform a server-by-server upgrade sequence, which is time-consuming and dependent on manual coordination. This enhancement would introduce an automated rolling upgrade capability that sequences the upgrade across servers in a multi-server deployment, keeping the platform available throughout the process. Automating this workflow would reduce the operational burden of manual upgrade coordination and allow customers running critical, high-availability environments to upgrade without service interruption.
