VMFS5.6 Space Reclamation

I have a 4TB datastore named "Prod4T", which is thin provisioned, there is a production VM running inside, and it consumes only 2.8TB spaces.
Is it safe to use the following command to reclam spaces in the Prod4T without cause any data loss?

esxcli storage vmfs unmap -l Prod4T

Many thanks.
