Release Planning Note

How to Upgrade
Prior to upgrading to this release, please read the Release Notes referenced above. As a best practice, IronPort recommends preparing for an upgrade by taking the following steps:
1. Save the XML configuration file off of the appliance.
2. If you are using the Safelist/Blocklist feature, export the list off of box.
3. Suspend the listeners.
4. Drain the mail queue and the delivery queue.
5. Re-enable the listeners after you upgrade.
Once you have read the Release Notes and followed the steps above, you may log into the command line of your IronPort Appliance as the 'admin' user, and type 'upgrade'. For systems on IronPort AsyncOS 4.5.0 or greater, you may use the GUI upgrade functionality in the "System Administration" tab. For systems on revisions greater than 3.8.3, 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 target 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.
