Upgrade ASA Failover Active/Standby

[youssef.ghoulab]

Hello everybody,

I have 2 ASA in Failover configuration, and I want to Upgrade them in a production time. I will follow the procedure of Zero Downtime Upgrade but I want to know if there is any way to Upgrade those Appliances without any cutoff session for the users.


Thank you

Hi Youseef,

You could enable stateful replications between the ASAs by configuring Stateful failover link. With that, your connections and VPN tunnels would also get replicated.

Bydefault, http connections are not replicated to standby unit. However, to enable those, give ' failover replication http' on both the ASAs.

Hope it helps.

Regards,
