>
> When beginning either a rolling or express upgrade, the API may take a long
> time to return from the following call:
> {code}
> POST api/v1/clusters/<cluster>/upgrades
> {
> "Upgrade": {
> "repository_version": "2.3.0.0-2545"
> }
> }
> {code}
> The web client should create a modal dialog while this call is in progress
> with a message like, "Preparing the Upgrade..." so that the administrator
> knows that something is going on. Once the POST returns, the dialog can be
> dismissed automatically.
