Hello,
We are using the NetApp Shift Toolkit as part of a VM migration project (from VMware to Proxmox).
I noticed that there are several “DRO” (Disaster Recovery Orchestrator) snapshots on the volumes. From my understanding, these are related to the Shift Toolkit, which creates a volume snapshot before converting the disks. It then creates a clone (FlexClone) to convert the disk format from .vmdk to .qcow2, without modifying the original virtual machine.
These snapshots are consuming a significant amount of storage space (more than 18 TB! on flash array for few tests). I assume they are temporary and expected to be automatically cleaned up.
Is it possible that some blueprints were not executed successfully and that the snapshots were therefore not properly cleaned up?
Are these snapshots intended to provide a rollback mechanism, allowing us to revert to the original VM running on VMware?
Could you please confirm whether my understanding is correct, and let us know whether these snapshots can be safely deleted when there is no migration process currently in progress?
Thank you in advance for your clarification.
Best regards,
