Upgrade Cisco Pix Firewall

Hi Randall,

Yes it can be upgraded very well, but just take care of the hardware requirements for PIX 8.x, youw ill find it here:

But first go to 7.2---> 8.x

Upgrade Cisco Pix Firewall


Thank you for your help.

I have one quick question, this pix is not in failover, it is standalone but it has Unrestricted license. It only has 64Mb of Ram. Will I have any problems based on your link recommendation?

Memory Requirements:

If you are using a PIX 515/515E running PIX Version 6.2/6.3, you must increase your memory before upgrading to PIX Version 8.0(2). This version requires at least 64 MB of RAM for Restricted (R) licenses and 128 MB of RAM for Unrestricted (UR) and Failover (FO) licenses

What is the difference between the restricted Licenses and the Unrestricted Licenses?

Hi Randall,

Thats correct, with the UR license you would need more RAM since there are more number of features enabled in this license which eats up more amount of memory.

Hope that helps.
