AsyncOS 9.6 for Email Security Release Notes

 

For further information on this release and others, please refer to the AsyncOS for Email Security Release Notes available on Cisco.com.

 

How to Upgrade

Prior to upgrading to this release, please read the Release Notes referenced above and save a copy of the configuration file somewhere other than directly on the appliance.

 

Once the Release Notes have been read and reviewed, log into the CLI of the Content Security Appliance as the 'admin' user and run upgrade, or use the GUI upgrade functionality, System Administration > System Upgrade.  The appliance may upgrade directly to the highest version available in the displayed list.

 

NOTE: It is important to follow the upgrade instructions available in the Release Notes. When upgrading, if the desired release version is not listed, the appliance may not be on a revision that is able to upgrade directly.  See 'Upgrade Paths' below.

 

Upgrade Paths

Please refer to the Release Notes for qualified upgrade paths.  If the appliance(s) are on any other AsyncOS revision, it may need to have multiple upgrades performed, as specified in the release notes. Only the immediate next step in the upgrade path will be shown, with the next revision being shown once the appliance is at appropriate provisioned version.

 

The following versions are available to upgrade directly to 9.6.0-042:

  • phoebe-8-5-6-106 -> phoebe-9-6-0-042
  • phoebe-8-5-7-042 -> phoebe-9-6-0-042
  • phoebe-9-1-0-032 -> phoebe-9-6-0-042
  • phoebe-9-5-0-201 -> phoebe-9-6-0-042
  • phoebe-9-6-0-030 -> phoebe-9-6-0-042

 

(*Please note – the new upgrade path from 8.5.7-042!)
