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 on your appliance.
Once you have read the Release Notes you may log into the command line of your IronPort Appliance as the 'admin' user, and type upgrade, or use the WebUI upgrade functionality in the 'System Administration' tab.
You may upgrade directly to the highest version available in the displayed list.
**NOTE** It is important that you follow the upgrade instructions available in the Release Notes. If you do attempt to upgrade and do not see the desired release version available, your appliance is likely not on a version allowed to upgrade directly. See 'Upgrade Paths' below.
Upgrade Paths
Please refer to the Release Notes for qualified upgrade paths. If your systems are on any other AsyncOS release, you will need to perform multiple upgrades as specified in the release notes. Only the immediate next step in the upgrade path will be shown to you, with the next revision being shown once you are at the approved level.
