      Right now we have 2 flows of the VMware migraitons.

      1. cold local migration
        1. Allocating the blank DataVolume
        2. CDI allocates the PVCs
        3. Conversion pod populates the PVCs and converts the pod both using the virt-v2v
      2. warm/remote migration
        1. Create the CDI DataVolume with the disk image
        2. CDI allocates the PVC
        3. CDI transferes the disk
        4. The conversion pod only runs the virt-v2v-in-place and only converts the guest

      We are using 2 different flows which can cause problems with different behavior. For example the CDI transfers each disk in parallel whereas the virt-v2v transfers the disks in sequence. So the migration of single VM with multiple disks could be faster using the warm/remote migration flow.

      We should investigate if it would be worth if to migrate into single flow using the CNV CDI.
