Description of problem:
VM disk contained 2 images. Base and Active/LEAF. Only the base image appears to have migrated to the dst SD and no indication that Active/LEAF move was initiated. Once the COPY task was deemed successful, the source images were purged which included the Active/LEAF that wasn't moved. This rendered VM not to boot and missing data.
