Cancel WLC upgrade before rebooting

[saulov8]

I have downloaded a new image to a virtual WLC but before rebooting the controller, I pre-downloaded the image to the APs.

Some APs are getting the status None on the Predowload Status.

During my investigation I found that those APs are not supported by the new WLC image.

I still haven't rebooted the WLC and the APs.

How can I cancel the upgrade so if the WLC happens to reboot, it won't install the new image?

Upload the current firmware up to the controller.

Leo is right. You really should upload the image twice to flush out the new image you uploaded, then make sure you upload to the ap’s again. Alsway review the release notes or the wlc matix before you upgrade, purchase new equipment, etc., so you know if there is any compatibility issues.
