I am trying to reclaim zero space on several Windows VMs. I have already ran sDelete and completed a storage VMotion however the VMDK stays at full storage usage even though it is thin. I can run punchzero and reclaim the space however I am looking for a way to do it without the down time. We are running ESXi6.5 with a mix of VMFS5 and VMFS6 datastores.

The above article and many others state that it should be possible so I am wondering what I am missing in the process.
