Cisco Cisco Web Security Appliance S680

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. 

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.  

Generally, configuration files from earlier AsyncOS releases are incompatible with later AsyncOS 
releases and vice-versa. 

The encryption strength of the demo security certificate is 1024 bits both before and after upgrade to 
AsyncOS 8.5 and later. 

You must reboot the Web Security appliance after you upgrade AsyncOS for Web.

This section describes changes in behavior from previous versions of AsyncOS for Web that may affect 
the appliance configuration after you upgrade to the latest version.
