I have got two Cisco ASA 5510, where:
FW1 = Primary ASA
FW2 = Failover ASA
I am planning on upgrading the Firmware, for those ASA, but want to get minimal downtime possible.
Can I redirect all traffic to FW2 while FW1 gets upgraded, then back to FW1 while FW2 gets updated?
Or can I just upgrade FW1 and the failover mode will automatically know that FW1 is under maintenance and will redirect all the traffic to the FW2 by itself? Cheers!
Solved! Go to Solution.

Hello,
The traffic shifting between the firewalls can be done manually or automatically once a fw senses that other has failed. You can do a zero downtime upgrade, please follow the below doc:
Just stick to the upgrade path, details of which are in the link.
