Memory Requirements

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.

Software Requirements

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.
