To migrate firewall configuration file
Validate that your old firewall is part of the supported set listed and click Next to start the wizard.
Click Next.
Select the firewall model you want to configure from the SELECT TARGET PRODUCT list.
The selected product displays in SELECTED PRODUCT pane. You can read more about that product by using the forward and back arrows to navigate the specifications. Click on the link for More Specs to see the product page for that firewall.
Click Next.
Click Next.
Click Finish. The old file is converted based on the parameters you gave. When done the new file is downloaded so you save it to your local system.
You should reset the firewall to factory defaults before importing the configuration file (not required if the device is fresh out of the box).
