Joining Cisco WSAs to an appliance group simplifies the task of patching multiple appliances. An appliance group is a collection of WSAs that share the same configuration settings and software versions. Administrators can use appliance groups to apply configuration changes and software updates to multiple WSAs at once, instead of performing these tasks individually for each appliance12. This reduces the administrative overhead and ensures consistency across the WSAs. References:
