I want to upgrade my pix IOS from 6.4 to pix724. Please let me know is there any limitation on this process and steps necessory to perform this.
Do I need to upgrade the Flash or Ram
Currently the PIX I have is
Cisco PIX Firewall Version 6.3(4)
Hardware: PIX-515, 32 MB RAM, CPU Pentium 200 MHz
Flash i28F640J5 @ 0x300, 16MB
I think that I saw this same posting in Network Infrastructure board. If not, here is what my reply was:
If you are using a PIX 515/515E running PIX Version 6.2/6.3, you need to upgrade your memory before performing an upgrade to PIX Version 7.0. PIX Version 7.0 requires at least 64 MB of RAM for Restricted (R) licenses and 128 MB of RAM for Unrestricted (UR) and Failover (FO) licenses. The following security appliance platforms require at least 64 MB of RAM.
Version 7.2(4) requires the following:
1. The minimum software version required before performing an upgrade to PIX Version 7.2(4) is PIX Version 7.0. If you are running a PIX version prior to PIX Version 6.2, you must first upgrade to PIX Version 6.2 or PIX Version 6.3 before you can begin the upgrade to PIX Version 7.0.
Hope this helps. Please rate.
