      2) start the migration, plan is hang on "ImageConversion phase", conversion pod and pvc are Pending status, more details in attached file: plan-cold-win2019-errorsc.yaml, pod-cold-win2019-errorsc-vm-1017-qth76.yaml, persistentvolumeclaim-cold-win2019-errorsc-vm-1017-qth76-conversion-temp-storage.yaml

      $ cat pod-cold-win2019-errorsc-vm-1017-qth76.yaml|grep status -A 10
       status:
        phase: Pending
        conditions:
          - type: PodScheduled
            status: 'False'
            lastProbeTime: null
            lastTransitionTime: '2026-02-04T19:57:43Z'
            reason: Unschedulable
