Cisco Cisco Email Security Appliance C160

Requirements for obtaining technical support for your virtual appliance are described in the Cisco 
Content Security Virtual Appliance Installation Guide available from 

. 

Please contact Cisco TAC for information required to provision your virtual appliance. 

Before upgrading, review the following:

If you have manually created a policy quarantine with the name “File Analysis,” you must eliminate 
this quarantine before upgrading from a release earlier than AsyncOS 9.0. 

You can do this by creating another quarantine with a different name, moving the messages to this 
new quarantine, then deleting the existing File Analysis quarantine. For more information about 
moving messages between policy quarantines, see the user guide or online help. 

If you do not do this, the system will not create the File Analysis quarantine that is used to 
automatically process messages sent for analysis. 

After upgrade, and after you configure the system to send messages to the new system-created File 
Analysis quarantine, you may want to delete, or disable in your incoming mail policies, any content 
filters that you previously created to quarantine messages with files sent for analysis.

AsyncOS 9.5 and 9.6 releases are not FIPS compliant releases. If you have enabled FIPS mode on your 
appliance, you must disable it before upgrading to AsyncOS 9.5 or 9.6.

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.
