I have a very silly doubt.
If I have a stateful high availability upgrade license, is it added on the primary appliance?
Thank you for visiting SonicWall Community.
Yes, the Stateful HA should be licensed only on the Primary unit if you have purchased it. Secondary HA appliance need not to have the Stateful HA license.
This info can be confirmed on the MySonicWall account to which the appliances are registered or from the SonicWall GUI itself under System | Licenses page.
Hope this helps.
For that login to the mysonicwall account and locate your product and verify the HA license is added or not.
