350 Implementing the IBM Storwize V5000 Gen2 with IBM Spectrum Virtualize V8.1
7.1 Storage migration wizard overview
The storage migration wizard uses the Volume Mirroring functionality to allow reads and
writes during the migration, eliminating 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:
To redistribute workload within a clustered system across the disk subsystem
To move workload onto newly installed storage
To move workload off old or failing storage, ahead of decommissioning it
To migrate data from an older disk subsystem to Storwize V5000 Gen2
To migrate data from one disk subsystem to another disk subsystem
Specifically, this chapter provides information about the following topics:
Interoperation and compatibility

7.2 Interoperation and compatibility
Interoperation is an important consideration when a new storage system is deployed into an
environment that already has an existing storage infrastructure. This section describes how to
check that the existing storage environment, the storage system and the 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 need to 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
need to select the storage version and define the external storage that will be attached to the
Storwize V5000 Gen2.
Command-line interface (CLI): For more information about the command-line interface
setup, see Appendix A, “CLI setup and SAN Boot” on page 801.
Manually migrating data: For more information about migrating data manually, see
Chapter 11, “External storage virtualization” on page 641.
