Looking to roll back a classroom controller to 4.0. Is it possible to roll backwards both Primary and backup images to 4.0 (to prevent students booting to 4.1) 4402 controller.
You can downgrading from 4.1 to the 4.0 release. But it will result in the config needing to be re-entered. The config changes in 4.1 will not carry over to the 4.0 release when downgrading.
