Prepare for PDM

If the PIX Firewall unit shipped with PIX Firewall software Version 6.2 or higher, PDM v2.1 is already installed in the Flash memory. Otherwise, the following steps should be taken before you install PDM v2.1:

• When performing an upgrade, you must get the PDM software from Cisco using the same methods and, typically, at the same time as securing upgraded PIX Firewall OS software. That process is covered in the last two sections of this chapter.

• Save the PIX Firewall configuration by issuing a write terminal command to display the configuration, and then use cut-and-paste to save it to a text file.

• Record the activation key. One method would be to use cut-and-paste with the show version command to save it to a text file.
