text: **7.7.2 Volume migration by adding a volume copy**
  
  IBM Spectrum Virtualize supports creating, synchronizing, splitting, and deleting volume 
  copies. A combination of these tasks can be used to migrate volumes to other storage pools. 
  
  The easiest way to migrate volume copies is to use the migration feature that is described in 
  7.7, “Migrating a volume to another storage pool” on page 281. However, in some use cases, 
  the preferred or only method of volume migration is to create a copy of the volume in the 
  target storage pool and then remove the old copy. 
  
  **Note:**You can specify storage efficiency characteristics of the new volume copy differently 
  than these of the primary copy. For example, you can make a thin-provisioned copy of 
  a fully provisioned volume. 
  
  This volume migration option can be used only for single-copy volumes. If you need to 
  move a copy of a mirrored volume by using this method, you must delete one of the volume 
  copies first, and then create a copy in the target storage pool. This process causes a 
  temporary loss of redundancy while the volume copies synchronize. 
  
  To migrate a volume using the volume copy feature, complete the following steps: 
  1. Select the volume that you want to move, and click**Actions**→**Add Volume Copy**, as 
  shown in Figure 7-47.
