Upgrading Firmware 
Dell SonicWALL recommends that you run the latest available 
firmware on your security appliance. You will need to upgrade 
the factory-installed firmware to the latest version available on 
MySonicWALL.
The following procedures are for upgrading an existing 
SonicOS firmware image to a newer version: 
Saving a Backup Copy of Your Preferences
Before beginning the update process, make a system backup 
on your Dell SonicWALL appliance. The backup feature saves a 
copy of the current system state, firmware, and configuration 
settings on your Dell SonicWALL security appliance, protecting 
all your existing settings in the event that it becomes necessary 
to return to a previous configuration state. 
In addition to creating a system backup, you can export the 
configuration preferences file to your local management station. 
This file serves as an external backup of the configuration 
preferences, and can be imported back into the 
Dell SonicWALL security appliance if it is necessary to reboot 
the firmware with factory default settings. 
Perform the following procedures to save a system backup on 
your appliance and export configuration settings to a file on your 
local management station: 
1.
On the System > Settings page, click Create Backup
SonicOS takes a “snapshot” of your current system state, 
firmware, and configuration preference, and makes it the 
new System Backup firmware image. Clicking Create 
Backup
 overwrites the existing System Backup image, if 
any. The System Backup entry displays in the Firmware 
Management 
table. 
2.
To export your settings to a local file, click Export Settings
A popup window displays the name of the saved file.
