Cisco Cisco Web Security Appliance S670 User Guide

Before you revert AsyncOS for Web, back up the following information from the Web Security appliance 
to a separate machine:

System configuration file.

Log files you want to preserve.

Reports you want to preserve.

Customized end-user notification pages stored on the appliance.

PAC files stored on the appliance.

Save a backup copy of the current configuration of your appliance (with passwords unmasked) on 
another machine.

This is not the configuration file that will be loaded after reverting.

Back up to a separate machine any of the following files that you might want to preserve:

Log files

Reports

Any customized end-user notification pages stored on the appliance

Any PAC files stored on the appliance

Log into the CLI of the appliance you want to revert.

When you run the 

revert

 command in the next step, several warning prompts are issued. After these 

warning prompts are accepted, the revert action takes place immediately. Therefore, do not begin the 
reversion process until after you have completed the pre-reversion steps. 

From the CLI, enter the 

revert

 command.

Confirm twice that you want to continue with the reversion.

Choose one of the available versions to revert to.

The appliance reboots twice.

The reversion process is time-consuming. It may take fifteen to twenty minutes before reversion 
is complete and console access to the appliance is available again.

The appliance should now run using the selected AsyncOS for Web version. You can access the web 
interface from a web browser.
