Cisco Cisco Email Security Appliance C190

Load the configuration file from the hardware appliance onto the virtual appliance. 

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. 

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. 

Please be aware of the following upgrade impacts:

For DKIM Authentication, Cisco currently supports version 8 of the Draft Specification of 
‘Authentication-Results:’ header.

For SPF/SIDF verification, the 

spf-passed

 rule is no longer available in content filters. To maintain 

backwards compatibility, the spf-passed content filter rule will be accepted from XML configuration 
files but it will be converted to the spf-status rule with corresponding arguments. spf-passed will be 
changed to spf-status == "Pass" and NOT spf-passed to spf-status != "Pass". You can, however, still 
use the spf-passed message filter.
