Using upgrade tool I'm trying to convert an autonomous AIR-AP1242AG-A-K9 AP to LWAPP but the upgrade fails when it tries to load the recovery image onto the AP. Has anyone run into this issue and if so what is the fix? Running 12.3(11)JA IOS on the AP.
Load the Autonomous IOS using the mode button method. Once the IOS is up and running, copy the recovery image using the "copy tftp: flash:" and change the boot parameters to boot the recovery image.
Once the AP boots the recovery image, make sure the AP can ping the Management IP Address of the WLC and use the command "lwap ap controller ip address ".
Hope this helps.
