I received the following error message when trying to deploy the changes to the device:
CEDT0031: no command is available to download for the device X.X.X.X. REmove the device from the job and try again.
You can't do that. Instead, just remove "aaa new-model" from the config then try to deploy it. Alternatively, you can try "merge mode," but that will send the whole config back to the device.
