In vSphere 5.x, virtual machine storage policies were called storage profiles and had a different format. When you upgrade the vSphere environment from a 5.x version to vSphere 6.x, storage profiles that you created in the earlier versions are converted to storage policies.

All the components of legacy storage profiles are transformed into new formats or objects. Any system-defined storage capabilities are converted into storage-specific data services based on metadata. User-defined capabilities become datastore tags.
