Upgrade using Helm chart.
The procedure outlined following assumes that the installed Helm

To update the local Helm repository and upgrade NDB Operator to the latest version, execute the following helm commands:
> helm repo update > helm upgrade --namespace=ndb-operator ndbop ndb-operator-repo/ndb-operator
If the namespace in which NDB Operator is installed is other than
