Release Notes for AsyncOS 9.7.2 for Cisco Email Security Appliances
 
  Installation and Upgrade Notes
Reverting to Previous AsyncOS Versions
The following AsyncOS versions are affected by the Internal Testing Interface Vulnerability
(
):
9.1.2-023
9.1.2-028
9.1.2-036
9.7.2-046
9.7.2-047
9.7-2-054
If you upgrade to either AsyncOS 9.7.2-131 or AsyncOS 9.7.2-065 from one of the above versions, you 
cannot revert to any of the previous versions.
FIPS Compliance
AsyncOS 9.7.x release is not a FIPS compliant release. If you have enabled FIPS mode on your 
appliance, you must disable it before upgrading to AsyncOS 9.7.x.
Upgrading Deployments with Centralized Management (Clustered Appliances) 
If a cluster includes C160, C360, C660, or X1060 hardware appliances, remove these appliances from 
the cluster before upgrading. 
All machines in a cluster must be running the same version of AsyncOS, and x60 hardware cannot be 
upgraded to this release. If necessary, create a separate cluster for your x60 appliances. 
Upgrading From a Release Other Than the Immediate Previous Release 
If you are upgrading from a major (AsyncOS X.0) or minor (AsyncOS X.x) release other than the release 
immediately preceding this release, you should review the Release Notes for major and minor releases 
between your current release and this release. 
Maintenance releases (AsyncOS X.x.x) include only bug fixes. 
Configuration Files
Cisco does not generally support the backward compatibility of configuration files with previous major 
releases. Minor release support is provided. Configuration files from previous versions may work with 
later releases; however, they may require modification to load. Check with Cisco Customer Support if 
you have any questions about configuration file support.
IPMI Messages During Upgrade
If you are upgrading your appliance using CLI, you may observe messages related to IPMI. You can 
ignore these messages. This is a known issue.
