Share Migration (Since API v2.5)
================================
As an administrator, you can migrate a share with its data from one
location to another in a manner that is transparent to users and workloads.
Possible use cases for data migration include:
- Bring down a physical storage device for maintenance without disrupting
workloads.
- Modify the properties of a share.
- Free up space in a thinly-provisioned back end.
.. note::
Share Migration APIs are part of the `experimental APIs
<http://developer.openstack.org/api-ref/shared-file-systems/
#experimental-apis>`_ .
Migrate share (versions 2.5 to 2.14)
=========================================
.. rest_method:: POST /v2/{tenant_id}/shares/{share_id}/action
Migrates a share from one back end to another.
You can migrate a share from one back end to another but both back
ends must set the ``driver_handles_share_servers`` parameter to
``False``. If a share driver handles one of the back ends, this
action is not supported. You can configure a back end in the
``manila.conf`` file.
