Reverting to an Earlier Version of AsyncOS

You can revert to an to a previous qualified version of AsyncOS for emergency
uses.

Because upgrades cause one-way transformation of key subsystems, the reversion
process is complex and requires qualification by Cisco IronPort Quality
Assurance teams. You can revert to one of the previous two versions only. The
earliest AsyncOS version supported for this functionality is AsyncOS 6.5; prior
versions of AsyncOS are not supported.

Important Note About Reversion Impact

Using the

revert

command on an IronPort appliance is a very destructive action.

This command destroys all configuration logs and databases. In addition, it
disrupts mail handling until the appliance is reconfigured. Because this command
destroys all configuration, it is highly recommended that you have physical local
access to the IronPort appliance when you want to issue the

revert

command.
