Seamless upgrades from an SMI-S based driver to RESTAPI based driver,
following the setup instructions above, are supported with a few exceptions:
#. OpenStack's ``live migration`` functionality will not work on already
attached/in-use legacy volumes without first migrating the volumes to
the new REST masking view structure. This can be done by running the
migrate.py script in PyU4V. Please refer to the Tools Guide in PyU4V_.
.. code-block:: text
$ pip install PyU4V
#. Seamless upgrade from SMI-S(Ocata and earlier) to REST(Pike and later)
is now available on all functionality including Live Migration. Please
see 1867163_ for more details.
#. Consistency groups are deprecated in Pike. Generic Volume Groups are
supported from Pike onwards.
