App layering appliance system OS upgrade

In version 2403 or earlier of the App Layering appliance the operating system used is CentOS 7, which is now end-of-life.

New with App Layering 2409 the appliance has been enhanced to run a modern version of Linux. The new appliance provides improved supportability, security compliance, and other benefits.

It is important to note that there is not an in-place upgrade from version 2403 or earlier to version 2409. You will need to download and deploy a new appliance running App Layering 2409, and then migrate your data from the old appliance to the new using the new appliance migration feature.

The migration feature has been added as an upgrade to App Layering 2403 which can be downloaded and installed manually or applied via the auto-upgrade feature within the product. Refer to the upgrade documentation for more information about how to upgrade the appliance.
