Vxrail VSAN datastore Migrate to PMAX datastore NOT exact storage usage after migrated.

Hi Dell support,

Good day,

We have a concern regarding storage vMotion. the Storage usages of VMs has been change after we migrated to Pmax datastore from 6TB it was changed to 2.9TB only now. however the migration was successful. is it normal storage usage smaller now and no files has been delete?
