Hi All, I have recently purchased the above-mentioned Cisco PIX Firewall on Ebay, upgraded the Cisco PIX 501 Firewall OS to version
6.3(4) and the PIX Device Manager(PDM) to version 3.02. The firewall is working very nicely without a hitch. My question is after upgrading the Cisco PIX OS to a newer version and the PDM to a newer version, do I need to upgrade the activation keys on the device? All the previous license features of the device before the upgrade were maintained after the upgrade.Thanks in advance, Benmark.
