upgrade from 3.1(1) to 3.1(6)

Unanswered Question
Nov 13th, 2008

Is it possible when running two FWSMs as a failover pair (active/standby) to upgrade from 3.1(1) to 3.1(6) without having any down time? can I simply fail the firewalls over manually and upgrade/reload each unit in turn working only on the standby unit.

I have this problem too.

The two units in a failover configuration must have the same major (first number) and minor (second number) software version. However, you can use different versions of the software during an upgrade process; for example, you can upgrade one unit from Version 3.1(1) to Version 3.1(2) and have failover remain active. We recommend upgrading both units to the same version to ensure long-term compatibility.You need to disable configuration synchronization when upgrading a software image or changing the configuration on the active FWSM to verify that the configuration files are complete before the configuration is synchronized with the standby FWSM configuration.
