When migrating, you must migrate host information, which can be done using the Scan Host Groups feature.
This feature enables you to automatically add servers into Ops Center Administrator from existing host groups in onboarded storage systems. (Ops Center Administrator creates or updates server objects based on host groups.) The Scan Host Group job uses host group information retrieved by using SVP and CCI.
Scan Host Groups does not change any storage configuration or related information (for example, path information). Existing information is maintained and only differential information is updated for server objects in Ops Center Administrator.
At a high level, the migration steps are as follows:
- Install and configure Ops Center Administrator on a new server.
- Onboard storage systems to Ops Center Administrator and temporarily manage storage systems using both products (existing product and Ops Center Administrator).
- Migrate host information using Host Scan Groups. For details on how to use Scan Host Group as well as specifics about behavior when migrating information from different environments, see "Scanning host groups" in the Hitachi Ops Center Administrator User Guide.
- As soon as you can manage the storage systems by using only Ops Center Administrator, disconnect the storage systems from the previous products.
