Getting "error while setting the configuration file encryption mode" while uploading IOS file or config file on Cisco WLC 5508 via TFTP server.

 1) What is the software version of the 5508 2) Is this the effective and or only error 'as displayed' or is something else shown ? 3) Does it work when another protocol-transfer method is being used (besides tftp), if available.

1. version is 8.2.1.29.

2. I want to configure new hardware with backup file downloaded from other 5508 WLC but not working.

3. IOS upload work with HTTPS option but showing disable for configuration file upload.

 - For the latter you may want to copy the config between the controllers without encrypting the source first.

There is bug issue in 8.2.1.29, so I upgraded to 8.3 via HTTP protocol. Post upgrading IOS able to upload config file to WLC via TFTP.
