Steps:

• Get a cluster with OCP 4.14, CNV 4.13 (HPP is default storage class)
• Edit one or two of HCO DataImportCron templates - add storage class ocs-storagecluster-ceph-rbd
• Delete the PVC, wait for it to re-import to OCS PVC
• Look at the DataSources, check that all of them Ready, Available
• Create a VM from the relevant DataSource, and connect to its console to make sure everything is fine
• Upgrade CNV to 4.14.0
• Check that OCS PVC was deleted, and VolumeSnapshot got created for it instead, that VolumeSnapshot is ReadyToUse: true
• Check all DataSources (also in UI), make sure they all are Ready, Available
• Create a VM from the DataSource (one from OCS Snapshot, one from HPP PVC), and connect to its console to make sure everything is fine
