We have two PIX firewalls (FO-UR licenses). The details are as below:

Cisco PIX Firewall Version 6.3(5)

Cisco PIX Device Manager Version 3.0(4)

Hardware: PIX-535, 1024 MB RAM, CPU Pentium III 1000 MHz

Flash i28F640J5 @ 0x300, 16MB

BIOS Flash DA28F320J5 @ 0xfffd8000, 128KB

Are there any issues related to upgrading version 6.3 to 7.22?

What will happen to the licenses? and the activation keys?

Please suggest.

You can go ahead you have enough memory for upgrade (1G RAM is required for 535)...

BUT its not recommended to upgrade straight to 7.2 - upgrade from 6.3 to 7.0 first , let the upgrade process convert the configuration file, then upgrade from 7.0 to 7.2

Licenses stay same like on 6.3

Following link could be helpful


It also depends if you have pdm installed or not

If not you can upgrade with copy tftp flash command if yes you need run upgrade from monitor mode

check following link



hope that helps rate if it does

Thanks for the tip, I will take care to upgrade to version 7.0 first and then to 7.2 version.

Because I am upgrading the version do I have to apply for license with Cisco again? The reason why I am asking is this because since the day the device was installed (one year back) I have not applied/registered the PIX firewall with Cisco for activation-key.

What is the issue regarding PDM? I have version 3.0(4) installed on the firewall and I configure the device using PDM only and not through command line.
