Why each option
In ESXi 6.x, creating new VMFS3 datastores is unsupported, but existing VMFS3 volumes can still be upgraded in place to VMFS5.
ESXi 6.x removed the ability to format new datastores with VMFS3; any new datastore provisioning must use VMFS5 or later, making VMFS3 creation officially unsupported in this release.
VMware provides a supported non-destructive in-place upgrade path from VMFS3 to VMFS5 via vSphere Client or esxcli, allowing legacy volumes to be migrated to benefit from VMFS5 features such as the unified 1 MB sub-block size.
Existing VMFS3 datastores remain fully mountable and operational on ESXi 6.x hosts - they are not unsupported for use, only the creation of new VMFS3 volumes is blocked.
The VMFS3-to-VMFS5 upgrade is explicitly supported by VMware and is the documented recommended path for administrators to modernize legacy storage volumes.
