Sorry,No you cant. :smileysad:
In order to convert iAP-105 to CAP your controller must have higher arubaos version. :smileysurprised:
From the release note:
An IAP can be converted to an ArubaOS Campus AP only if the controller is running ArubaOS 6.1 or later and to an
ArubaOS Remote AP only if the controller is running ArubaOS 6.1.4 or later.
hope that info helped u. :smileyhappy:
