Cisco Cisco Email Security Appliance C160

You can connect AsyncOS 9.8 to a Security Management appliance only if the AsyncOS version of the 
Security Management appliance is 9.6.0-077.

RSA Enterprise Manager is not supported on AsyncOS 9.8. If you are using RSA Enterprise Manager, 
before upgrading to AsyncOS 9.8, perform the following tasks:

Disable RSA Enterprise Manager.

Enable RSA Email DLP on your appliance(s).

Using RSA Email DLP, recreate the DLP policies that were configured in RSA Enterprise Manager.

For instructions, see the “Data Loss Prevention” chapter in the User Guide or the online help.

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. 

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. 

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.
