Previous article Configure Umbrella virtual appliance. Next article Step 3: Schedule a reboot of the controller and APs Now that we have upgraded the controller to the new release and pre-downloaded the new AP images, we will need to schedule a reload.
To do this insure that APs primary image is the new code, by executing: show ap image all If you need to swap between primary and backup, execute the following command: config ap image swap all confirm that the new image is active for Access Points.
For the purposes of this post, I have set it to reboot 1 minute 30 seconds from now and swap the default partition to the newer version of code and save the running-configuration before the reload reset system in image swap reset-aps save-config.

Now, if you are to reboot the WLC with the secondary image to be safe, swap the AP image too , the predownloaded image comes up immediately as soon as the AP joins.
However, if you were to rollback to the previous image, what you find is that the AP no longer has the old image and therefore redownloads from the WLC leading to prolonged service outage time to service the wireless clients which can be undesirable unless anticipated for during the maintenance window. Option 1. Option 2. Option 3. If none of the options are a viable workaround, ensure you allow sufficient time for the rollback to finish during the maintenance window.
If a slave AP fails to download the image from its master AP even after the slave retry count that you have configured is exhausted, the slave AP reaches out to the Cisco WLC to fetch the new image.
If you upgrade from a release that is prior to Release 7. After the upgrade to a Release 7. X image, the predownload functionality works as expected. The predownload failure is only a one-time failure. The FlexConnect Groups page appears. This page lists the FlexConnect Groups configured on the controller. You can manually assign master access points in the FlexConnect group by selecting the access points.
