If you're receiving an error message like this, is because there are some AP Zones that have been configured with an unsupported version.
Let's use for example the version 6.1.1
In the Upgrade guide, we can find this matrix stating which AP firmware will be unsupported:
To identify the AP Zone(es) with supported/unsupported firmware, select the AP Zone and scroll down to the Configuration tab.
To change the AP firmware configuration, slelect the AP Zone, click 'More' and then 'Change AP Firmware':
Select an AP firmware that will be supported in the controller.
It's recommended to use the latest AP patch available in the RUCKUS support site.
