   Note for future googlers, this change will break a helm chart upgrade if you installed the chart before this change due to podManagementPolicy in a StatefulSet being an immutable field.
   
   > Error: UPGRADE FAILED: cannot patch "pulsar-zookeeper" with kind StatefulSet: StatefulSet.apps "pulsar-zookeeper" is invalid: spec: Forbidden: updates to statefulset spec for fields other than 'replicas', 'template', and 'updateStrategy' are forbidden
   
   Set it back to the previous version with the below in your custom values file which I don't think does any harm for existing installs
   
   ```
   zookeeper:
     # Changed to Parallel by default in https://github.com/apache/pulsar-helm-chart/pull/203
     # However since we installed the chart prior to this and this field is immutable
     # set it back to the old value.
     podManagementPolicy: OrderedReady
   ```
