--- upgrade: - | Dell EMC ScaleIO has been rebranded to VxFlex OS. The drivers ``cinder.volume.drivers.dell_emc.scaleio.driver.ScaleIODriver`` will now be updated to ``cinder.volume.drivers.dell_emc.vxflexos.driver.VxFlexOSDriver`` in cinder.conf. Driver configuration options that start with ``sio`` should also be updated to ``vxflexos``. Existing sio configuration options will continue to work but will be removed in the V release. Online documentation will also change to reflect these changes.
