> When creating a downgrade, the web client is still passing IDs which are no longer supported:
> {code}
> Bad request received: The properties [Upgrade/from_version] specified in the request or predicate are not supported for the resource type Upgrade.
> {code}
> To initiate a downgrade, the following information can be passed:
> {code}
> {
>   "Upgrade": {
>     "skip_failures": "false",
>     "skip_service_check_failures": "false",
>     "skip_prerequisite_checks": "true",
>     "upgrade_type": "NON_ROLLING",
>     "direction": "DOWNGRADE"
>   }
> }
> {code}
> Notice that there's no need no specify a version; the downgrade by nature must work off of the last failed upgrade.
