Configuring Centralized Image Upgrades
The centralized image upgrade feature introduced in ArubaOS 6.3 allows the master controller to automatically
upgrade its associated local controllers by sending an image from a image server to one or more local
controllers. If your master controller supports different local controller models, you can upload different image
types to the server, and the centralized image upgrade feature will send the local controller only the type of
image that controller supports.
Configuring Centralized Image Upgrades
This feature can be configured on a master controller only, and supports up to 100 simultaneous downloads.
You can configure a centralized image upgrade using the WebUI or command-line interfaces.
Using the WebUI
1. Navigate to Maintenance > Controller> Image Management.
2. Click the Local Configuration tab.
3. Click the Enable checkbox to enable this feature. When this option is selected, the WebUI displays the
following centralized image configuration parameters.
