|

Seamless upgrades from an SMI-S based driver to REST API 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. If you are upgrading from Newton
|
||||
or Ocata to Pike or greater please contact `Dell EMC Support`_ and we
|
||||
will guide you through the process.
|
||||
#. Seamless upgrade from SMI-S(Ocata and earlier) to REST(Pike and later)
|
||||
is now available on all functionality including Live Migration.
|
||||
|
||||
#. Consistency groups are deprecated in Pike. Generic Volume Groups are
|
||||
supported from Pike onwards.
