7.1 Storage migration wizard overview 7.2 Interoperation and compatibility The storage migration wizard uses the Volume Mirroring functionality to allow reads and  writes during the migration, which eliminates disruption and downtime. After the end of the  migration, the external storage can be retired. The storage migration wizard can also be used  to migrate data from other Storwize systems, such as the Storwize V5000 Gen1 or Storwize  V3700. There are multiple reasons to use the Storwize V5000 Gen2 migration features: Specifically, this chapter provides information about the following topics: For more information:  For more information about the command-line interface setup, see  Appendix A, “CLI setup and SAN Boot” on page 797. For more information about migrating data manually, see Chapter 11, “External storage  virtualization” on page 607. Interoperation is an important consideration when a new storage system is deployed into an  environment that includes a storage infrastructure. This section describes how to check that  the storage environment, storage system, and IBM Storwize V5000 Gen2 are ready for the  data migration process. To ensure interoperation and compatibility across all the elements that connect to the storage  area network (SAN) fabric, check the proposed configuration with the IBM System Storage  Interoperation Center (SSIC). SSIC can confirm whether a solution is supported and provide  recommendations for hardware and software levels.  SSIC validates the components within a single storage solution. To confirm the interoperation  between multiple storage solutions, it is necessary to request separate validation for each of  them. To require an interoperation validation within SSIC website, you must select  IBM System  Storage Midrange Disk  in the Storage Family and select  Storwize V5000 Storage  Controller Support  in the Storage Model. After defining the physical storage information, you  must select the storage version and define the external storage that is to be attached to the  Storwize V5000 Gen2.  358  Implementing the IBM Storwize V5000 Gen2 with IBM Spectrum Virtualize V8.2.1 GLYPH<SM590000> Storage migration wizard GLYPH<SM590000> Interoperation and compatibility GLYPH<SM590000> To migrate data from one disk subsystem to another disk subsystem GLYPH<SM590000> To migrate data from an older disk subsystem to Storwize V5000 Gen2 GLYPH<SM590000> To move workload off old or failing storage, ahead of decommissioning it GLYPH<SM590000> To move workload onto newly installed storage GLYPH<SM590000> To redistribute workload within a clustered system across the disk subsystem
