Upgrading Failover Pairs

The two units in a failover configuration should have the same major (first number), minor (second
number), and maintenance (third number) software version.
However, you can have different maintenance versions of the software running on each unit and still
maintain failover support. You can upgrade from any maintenance release to any other maintenance
release within a minor release. For example, you can upgrade from 3.1(1) to 3.1(3) without first
installing the maintenance releases in between.
To ensure long-term compatibility and stability, we recommend upgrading both units to the same version
as soon as possible.
The FWSM does not support upgrading from between major or minor releases, for example, from 2.3 to
3.1, without downtime.
