Hi ,
I want to upgrade my following Firewalls.
Site1 :
Cisco PIX from 6.3(4) to 7.2(3){Redundant Hardware available)
Site2: Cisco ASA from 7.2(1) to 7.2(3)
with Redundant hardware available.
My Question : While doing this OS Upgrade activity Do we need Down time.My Failover is prefectly working fine when we shut down one device , other device is coming up with complete Auto failure.
Please suggest - Do i need any down time for this activity.

Hi,
Since your firewalls come with a failover peer, yes you can upgrade their IOS with zero downtime.
Please see "Performing Zero Downtime Upgrades for Failover Pairs" section in the link below:

hi,
If you aim to upgrade with zero downtime, i'm afraid no you can't.
Please have a look at "Table 42-1 Zero-Downtime Upgrade Support" in the document that i've already sent to you.
Cheers,
