Synchronizing Firmware
Selecting the Synchronize Firmware Upload and Reboot
checkbox allows the Primary and Backup SonicWALL security
appliances in HA mode to have firmware uploaded on both
devices at once, in staggered sequence to ensure that security
is always maintained. During the firmware upload and reboot,
you are notified via a message dialog box that the firmware is
loaded on the Backup SonicWALL security appliance, and then
the Primary SonicWALL security appliance. You initiate this
process by clicking on the Synchronize Firmware button.
Configuring HA License Overview
You can configure HA license synchronization by associating
two SonicWALL security appliances as HA Primary and HA
Secondary on MySonicWALL. Note that the Backup appliance
of your HA pair is referred to as the HA Secondary unit on
MySonicWALL.
You must purchase a single set of security services licenses for
the HA Primary appliance. To use Stateful HA, you must first
activate the Stateful High Availability Upgrade license for the
primary unit in SonicOS. This is automatic if your appliance is
connected to the Internet. See

License synchronization is used during HA so that the Backup
appliance can maintain the same level of network protection
provided before the failover. To enable HA, you can use the
SonicOS UI to configure your two appliances as a HA pair in
Active/Idle mode.
MySonicWALL provides several methods of associating the two
appliances. You can start by registering a new appliance, and
then choosing an already-registered unit to associate it with.
You can associate two units that are both already registered.
Or, you can select a registered unit and then add a new
appliance with which to associate it.
Note that after registering new SonicWALL appliances on
MySonicWALL, you must also register each appliance from the
SonicOS management interface by clicking the registration link
on the System > Status page. This allows each unit to
synchronize with the SonicWALL license server and share
licenses with the associated appliance.
