Abstract: In some embodiments, a method includes installing at an access point that (1) includes a first software image and (2) is operatively coupled to a network controller via network, a second software image different from the first software image. The method includes defining in response to the installation, a virtual client disposed in the access point. The virtual client is configured to send to the network controller via the network a first validation data unit that causes the network controller to send a second validation data unit to the access point if the first validation data unit is received by the network controller. The method also includes installing at the access point that includes the second software image, the first software image and uninstalling the second software image if the access point does not receive the second validation data unit in response to the first validation data unit.
