HA License Configuration Overview
You can configure HA license synchronization by associating
two SonicWall security appliances as HA Primary and HA
Secondary on MySonicWall.
You must purchase a single set of security service licenses for
the HA Primary appliance. To use Stateful HA, you must first
activate the Stateful High Availability license for the primary
unit in SonicOS. This is automatic if your appliance is
connected to the Internet. See Registering, Licensing, and
Upgrading on page 25.
License synchronization is used in a High Availability
configuration so that the Secondary appliance can maintain
the same level of network protection as the Primary, in case of
a failover.
