To deploy a virtual appliance, see the Cisco Content Security Virtual Appliance Installation Guide, 
available from 

In order to migrate your configuration, both the old and the new appliances must be running the identical 
AsyncOS version, including build number. The AsyncOS version you choose must be supported on both 
appliances. 

Set up your virtual appliance with a supported 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. 

If your hardware and virtual appliances have different IP addresses, deselect Load Network Settings 
before loading the configuration file. 

Commit your changes. 

Go to Network > Authentication and join the domain again. Otherwise identities won’t work. 

When you upgrade AsyncOS for Web from the web interface or Command Line Interface (CLI), the 
configuration is saved to file in the /configuration/upgrade directory. You can access the upgrade 
directory using an FTP client. Each configuration file name is appended with the version number, and 
passwords in the configuration file are masked so they are not human readable. (bug 47966)
