Can't change LWAP association to different Controller

Question

I have a customer with LWAPs that are associated to a specific controller. They want to change the controller it's associated to, but it keeps returning to the original controller. They've tried assigning the Primary controller via WCS/WiSM, resetting the AP to default config, then resetting the LWAP.....the LWAP still associates with original controller.
A new LWAP out of the box goes to the correct controller with no problem. So, there is still something in the previously assigned controller to an LWAP that is not being cleared. Can someone tell how we can do this?
Any help would be appreciated.

Hi Richard,
Sorry about that :(
You could try these two methods;
Configuring Static Parameters to Register the Access Point to a Controller
Using the password that the controller sent to the access point, enter into EXEC mode on the access point console. When the access point is running LWAPP or a recovery IOS image, you can configure the static IP address on the access point, the IP address on the controller, the access point hostname, and the default gateway IP address by entering these commands:
•lwapp ap ip address ip-addr subnet-mask
•lwapp ap controller ip address ip-addr
•lwapp ap hostname ap-hostname
•lwapp ap ip default-gateway ip-addr
The access point with a recovery IOS image uses the static controller IP address to register to the specified controller and download the current LWAPP image. After the access point successfully registers to the controller, it receives configurations from the controller. The access point static hostname and the IP address of the controller are deleted from the access point configuration file. However, the access point static IP address and the netmask and the default gateway IP address are not deleted.
When the access point is running a recovery IOS image, the commands to configure the static IP address on the access point, the IP address on the controller, the access point hostname, and the default gateway IP address are always enabled.
These commands are disabled in the following cases:
•When the access point is running an LWAPP image.
•When the access point has an LWAPP configuration file in NVRAM.
•When the access point is in REGISTERED state with the controller.
The access point console displays the following error message if you enter any of these commands when they are disabled:
"ERROR!!! Command is disabled."

But I think you will like the ideas here better (from Lynne, Dan and Richard);
