text: **Chapter 9. Storage migration**
  
  This chapter describes the steps that are involved in migrating data from an external storage 
  system to the capacity of the Storwize V7000 by using the storage migration wizard. Migrating 
  data from other storage systems to the Storwize V7000 consolidates storage. It also allows 
  for IBM Spectrum Virtualize features, such as Easy Tier, thin provisioning, compression, 
  encryption, storage replication, and the easy-to-use graphical user interface (GUI) to be 
  realized across all volumes. 
  
  Storage migration uses the volume mirroring functionality to allow reads and writes during the 
  migration, and minimizing disruption and downtime. After the migration is complete, the 
  existing system can be retired. Storwize V7000 supports migration through Fibre Channel 
  and internet Small Computer Systems Interface (iSCSI) connections. Storage migration can 
  be used to migrate data from other storage systems and IBM SAN Volume Controller.
