I am following the official docs and (CRD and CR) to deploy the percona cluster on minikube with kubernetes version as 1.18  
However I notice that when I apply my CR it fails with following error message in the operator logs:

```auto
create newStatefulSetNode: StatefulSet.apps \"minidatapool-pxc\" is invalid: spec.updateStrategy: Invalid value: apps.StatefulSetUpdateStrategy{Type:\"SmartUpdate\", RollingUpdate:(*apps.RollingUpdateStatefulSetStrategy)(nil)}: must be 'RollingUpdate' or 'OnDelete'

```

And in my CR I am using

```auto
&nbsp; updateStrategy: SmartUpdate<br>

```

Any idea what me be wrong here?  
ThanksSachin

Hi @sjmittal  
looks like the old version of Operator is used.  
can you share full log of the Operator and full CR content
