the class VPlexDeviceController method migrateVirtualVolume.

/**
 * Creates and starts a VPlex data migration for the passed virtual volume
 * on the passed VPlex storage system. The passed target is a newly created
 * backend volume to which the data will be migrated. The source for the
 * data migration is the current backend volume for the virtual volume that
 * is in the same varray as the passed target. The method also creates
 * a migration job to monitor the progress of the migration. The workflow
 * step will complete when the migration completes, at which point the
 * migration is automatically committed.
 *
 * @param vplexURI
 *            The URI of the VPlex storage system.
 * @param virtualVolumeURI
 *            The URI of the virtual volume.
 * @param targetVolumeURI

 * @param migrationURI

 *            when a local virtual volume is being migrated to the other
 *            cluster, or null.
