title: Helm Error: UPGRADE FAILED: rendered manifests contain a new resource that already exists
body: <p>I have this error when the previous upgrade failed.</p>
  
  <p>I cannot upgrade without deleting manually all my pods and services.</p>
  
  <pre><code>Error: UPGRADE FAILED: rendered manifests contain a new resource that already exists.
  Unable to continue with update: existing resource conflict: namespace: ns-xy, name: svc-xy, existing_kind: /v1, Kind=Service, new_kind: /v1, Kind=Service
  </code></pre>
  
  <p>I tried with <code>helm upgrade --force</code> but with no success.</p>
  
  <p>One solution is to delete all the services and deployments updated, but that's long and creates a long interruption.</p>
  
  <p>How can I force the upgrade?</p>
