Upgrading a High Availability Pair

SonicOS on NSv Series supports High Availability (HA) on VMware ESXi, Hyper-V, KVM, and Azure platforms.

HA Stateful Synchronization is supported, which means that the secondary unit will automatically synchronize with the primary unit when SonicOS is updated on the primary. Simply upgrade the primary unit as described in Upgrading SonicOS with Current Settings.

However, when upgrading a High Availability pair using System Update, upgrade each unit individually. See the Upgrading via System Update in the NSv Management Console for details.
