i have pix 515E in failover mode with ver 6.3.5. Though i will be replacing those with ASA in next one year time, i want to know if there are reasons(security caveats, vpn compatability etc) for upgrading pix version to 8.x in the interim. I do not need to use any additional features that might come with ver 8.x.
If i have to upgrade to ver 8.x (after first upgrading to ver 7.2), do i have to re-write confiuration manually or are there tool available that converts the configuation?
Thanks in advance.
