    VMFS 5 and VMFS 6 can coexist. However, due to the changes done in VMFS 6 metadata structures to make it 4K aligned, you cannot inline/offline upgrade from VMFS5 to VMFS6.

    You can leverage the new VMFS 6 capabilities by creating a new VMFS 6 datastore and provisioning new virtual machines to it or migrating the existing virtual machines from VMFS 5 datastore to VMFS 6 datastore.

    Note: PowerCLI cmdlet “Update-VmfsDatastore” can be used to update datastore from VMFS 5 to VMFS 6.

    For more details and limitations on this cmdlet please refer to PowerCLI version 6.5.4 documentation.
