## 7.1 Storage migration wizard overview 

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: 

GLYPH<SM590000> To redistribute workload within a clustered system across the disk subsystem 

GLYPH<SM590000> To move workload onto newly installed storage 

GLYPH<SM590000> To move workload off old or failing storage, ahead of decommissioning it 

GLYPH<SM590000> To migrate data from an older disk subsystem to Storwize V5000 Gen2 

GLYPH<SM590000> To migrate data from one disk subsystem to another disk subsystem 

Specifically, this chapter provides information about the following topics: 

GLYPH<SM590000> Interoperation and compatibility

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. 

## 7.2 Interoperation and compatibility 

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.
