Configuring Centralized Image Upgrades

The centralized image upgrade feature allows the Mobility Master to upgrade itself and its associated managed devices by sending an image from the image server to one or more managed devices.

The Mobility Master connects to an image server, downloads the image file for each managed device, and verifies the validity of the image files. After the Mobility Master verifies the validity of the image files, the managed devices connect to the image server, download the appropriate image file, and upgrade to the downloaded image file.
