I am looking at upgrading a 515E to 7.2(X) release but I am wondering about the memory requirements. The PIX in question has 64MB Ram/16MB Flash, UR and FO licensing. I keep seeing in the memory requirements that it needs to be a minimum of 128MB Ram to maintain the licensing but I have another PIX firewall that was upgraded(by another tech) to 7.2(2)14 that is also 64/16 with the same licensing structure and it appears that all the licensing remained intact after the upgrade. I am a bit confused by the memory requirements and am wondering if I should be concerned.
Thanks for the reply. Currently the customer is not in the position to upgrade the RAM or replace the firewall. The logic behind the upgrade is that they have hit the limit on interfaces 6.3(5) will support(VLAN/Physical)and the only workaround I see is a code upgrade at this point in time.
