text: **9.1.1 Interoperability and compatibility**
  
  Interoperability is an important consideration when a new storage system is set up in an 
  environment that contains storage infrastructure. Before attaching any external storage 
  systems to the Storwize V7000, see the IBM System Storage Interoperation Center (SSIC). 
  
  At the SSIC site, select**IBM System Storage Midrange Disk**as the Storage Family, then 
  **Storwize V7000 Storage Controller Support**as the Storage Model. You can then refine 
  your search by selecting the external storage controller that you want to use in the**Storage**
  **Controller**menu. 
  
  The matrix results indicate the external storage that you want to attach to the Storwize V7000, 
  such as minimum firmware level or support for disks greater than 2 TB. 
  
  **9.1.2 Prerequisites**
  
  Before the storage migration wizard can be started, the external storage system must be 
  visible to the Storwize V7000. You also need to confirm that the restrictions and prerequisites 
  are met. 
  
  Administrators can migrate data from the external storage system to the system that uses 
  iSCSI connections and Fibre Channel or Fibre Channel over Ethernet connections.
