Cisco Cisco Email Security Appliance C160

If you have a previous Email Security Virtual Appliance release and you want to use more than 2 TB of 
disk space, you cannot simply upgrade your virtual appliance. Instead, deploy a new virtual machine 
instance for this release. You can maintain the old instance separately, and optionally manage both 
instances using a Cisco Content Security Management appliance. 

When you upgrade a virtual appliance, the existing licenses remain unchanged. 

Set up your virtual appliance with this AsyncOS release using the documentation described in 

. 

Upgrade your hardware appliance to this AsyncOS release. 

Save the configuration file from your upgraded hardware appliance 

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. 

Before upgrading:

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.
