CSI operator: different operator version if install is via OLM or Manual ?

Customer tried to install dell-csi-operator for OpenShift 4.6 version (with storage Dell EMC Unity) using both OLM and manual method according to Dell Github page:

https://dell.github.io/storage-plugin-docs/docs/installation/operator/

Using the "OLM method" the version installed is:

 -----

operator image: dellemc/csi-operator:1.2.0.000R

-----

and parameters on CSIUnity resource are the following:

spec:

  driver:

    common:

      envs:

        - name: X_CSI_UNITY_DEBUG

          value: 'true'

      image: 'dellemc/csi-unity:v1.4.0.000R'

      imagePullPolicy: IfNotPresent

    configVersion: v3

 

while installing via "manual method" the operator version got installed is:

operator image: dellemc/csi-operator:1.4.0.000R

Why two different version ?

In manual installation what is the correct csi unity yaml file to use considering OpenShift version 4.6 ? 

Also customer could upgrade OpenShift to 4.7, in this case what is the procedure to upgrade Unity CSI ?

 

thanks
