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. This chapter includes the following topics: Note:  This chapter does not cover migration outside of the storage migration wizard. To  migrate data outside of the wizard, you must use Import. For more information about the  Import action, see Chapter 6, “Storage pools” on page 191.
