. 

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. 

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. 

Cisco does not generally support the backward compatibility of configuration files with previous major 
releases. Minor release support is provided. Configuration files from previous versions may work with 
later releases; however, they may require modification to load. Check with Cisco Customer Support if 
you have any questions about configuration file support.

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