How to Update Serial Number and Model on Stand-alone and HA Appliances

You can change the serial number and model of CloudGen Firewall appliances configured as stand-alone units or as a High Availability cluster. Changing the serial number is necessary when you receive a new license for a different model, for example when upgrading from a level 2- to a level 4 firewall in the cloud.

Before You Begin

• (new appliances only) Locate the license token in the email you received from Barracuda Networks Customer Services after purchasing your CloudGen Firewall license, and activate the license. For more information, see How to Activate and License a Stand-alone Hardware CloudGen Firewall Appliance and How to Activate and License a Stand-Alone Virtual or Public Cloud Firewall or Control Center.
