I've had a WLC 2006 for a while. Just purchased the WLC 2106 as an upgrade. Is it possible to copy the config of the 2006 to the 2106? I don't want to have to manually recreate the WLANs and reassociate the APs with the new controller. I have tried saving the 2006 config to a TFTP server and uploading it to the 2106, but I get an error saying file type is not supported.
