NetApp Eseries - Migration not working correctly

[Yogesh]

Steps to reproduce -
1. Setup the env for multiple backends.
2. Create a cinder volume on c-mode/7-mode or DFM backend.
3. Perform the migration using 'cinder migrate' command to E-Series backend.
4. Once the migration is completed, try to perform some operation on migrated volume e.g. extend the volume size. or delete the volume.

Expected Result -
Any operation supported by normal volume should be supported by migrated volume.

Actual Result -
While trying to extend the size of the migrated volume, it throws an error -

    NetApp fix vol migration unusability

    in which the volume became unusable after successfull inbound
    migration due to volume id usage instead of name_id.
