 One way to perform the upgrade is to run:
 ```
-kubectl delete sts <RELEASE_NAME>-keycloak && helm upgrade --install 
+kubectl delete sts <RELEASE_NAME>-keycloak && helm upgrade --install
 ```
 This ensures that all replicas are restarted with the same version.
 Note that all sessions are lost in this case, and users might need to login again.
