A corresponding image-mode volume is now available in the same migration pool, as  shown in Figure 4-64. The image-mode volume can then be mapped to the original host mode. The data is still  physically present on the physical disk of the original external storage controller system  and no automatic migration process is running. If needed, the image-mode volume can be  migrated manually to another storage pool by using volume migration or volume mirroring  later. If this method is selected, choose the storage pool to hold the new volume and click  Import , as shown in Figure 4-65. Only pools with sufficient free extent capacity are listed. GLYPH<SM590000> The Migrate to an existing pool option starts by creating an image-mode volume as the  first method. However, it then migrates the data from the image-mode volume onto  another volume in the selected storage pool. After the migration process completes, the  image-mode volume and temporary migration pool are deleted.
