Important

From the sidebar, select Devices.
- Select the access controller you want to promote or select on the access controller and choose View Details.
- On the access controller details screen:
- Select and choose Promote Controller.
- Select the controller model to promote to from the list.
- Select Save to save the change.
- When you confirm promoting the controller, this will initiate controller synchronization.
