I am aware of how to manually upgrade AP's via SSH and have done so many times. A customer has raised a concern that any manually created files on the internal memory of the AP remain in place even after upgrade. In some case I would imagine this should be useful, but in our case I am trying to find out if there is an option to upgrade the firmware on an AP and perform a full data wipe as part of the process. I think the concern here is that AP's can potentially be filled up with Junk and affect their performance or that maliciuos files on internal memory could impact security. An option to do a full format upgrade across the estate could provide a clean slate and if thats an available option I suspect many customers would benefit.
Any thoughts anyone?
