the class BlockService method changeVolumeVirtualPool.

/**
 * Allows the caller to change the virtual pool for the volume identified in
 * the request. Currently, the only virtual pool changes that are supported
 * are as follows:
 *
 * Change the virtual pool for a VPLEX virtual volume. This virtual pool
 * change would allow the caller to change the types of drives, for example,
 * used for the backend volume(s) that are used by the virtual volume.
 *
 * Change the virtual pool for a VPLEX virtual volume, such that a local
 * VPLEX virtual volumes becomes a distributed VPLEX virtual volume.
 *
 * Change the virtual pool of a VMAX or VNX Block volume to make the volume
 * a local or distributed VPLEX virtual volume. Essentially, the volume
 * becomes the backend volume for a VPLEX virtual volume. Similar to
 * creating a virtual volume, but instead of creating a new backend volume,
 * using the volume identified in the request. The VMAX or VNX volume cannot
 * currently be exported for this change.
 *
 * Change the virtual pool of a VMAX or VNX Block volume to make the volume
 * a RecoverPoint protected volume. The volume must be able to stay put, and
 * ViPR will build a protection around it.
 *
 * Change the virtual pool of a VMAX or VNX Block volume to allow native
 * continuous copies to be created for it.
 *
 * Change the virtual pool of a volume to increase the export path parameter max_paths.
 * The number of paths will be upgraded if possible for all Export Groups / Export Masks
 * containing this volume. If the volume is not currently exported, max_paths can be
 * decreased or paths_per_initiator can be changed. Note that changing max_paths does
 * not have any effect on the export of BlockSnapshots that were created from this volume.
 *
 * Change the virtual pool of a VMAX and VNX volume to allow change of Auto-tiering policy
 * associated with it.
 * <p>
 * Since this method has been deprecated use POST /block/volumes/vpool-change
