> There are currently several ways of starting upgrades / downgrades:
> - The use of a directive on the request
> {noformat}
> http://localhost:8080/api/v1/clusters/c1/upgrades?downgrade=true
> {noformat}
> - The POST body JSON
> {noformat}
> {
> "RequestInfo": {
>   "downgrade": "true"
>   },
> "Upgrade":{
>   "from_version": ...
>  }
> }
> {noformat}
> The directive is confusing and can allow multiple downgrades or upgrades to be scheduled concurrently. It should be removed for consistency and the {{Upgrade/direction}} property should replace it.
