Migration
Storwize to FlashSystem Migration
A planning guide for moving from Storwize V3700, V5000, V7000, and older FlashSystem arrays into a modern IBM FlashSystem design.
Storwize search demand is still active because real environments do not retire on IBM's announcement calendar. Buyers often need to know what a V3700, V5000, or V7000 should become, what can be virtualized, and what outage or replication path is realistic.
Migration planning map
| Existing State | Likely Question | Planning Direction |
|---|---|---|
| Storwize V3700 | Is a compact FlashSystem enough? | Start with capacity, host count, latency, support status, and snapshot needs. |
| Storwize V7000 | Is this a 7300, 7600, or 9600 class replacement? | Check controller load, ports, pools, replication, and virtualization dependencies. |
| FlashSystem 5200 or 5300 | Refresh or expand? | Compare support term, FCM generation, effective capacity, and new Storage Assurance options. |
| Mixed vendor arrays | Can FlashSystem modernize the estate? | Evaluate external virtualization, migration method, monitoring, and service-level consistency. |
IBM Storage Virtualize is the key modernization layer. The buyer question is not only what new array to purchase, but whether the new system can simplify management, migration, and resilience across what is already installed.
