Configuring Data Migration

Configuring Data Migration

After a heterogeneous storage system (legacy storage system) is replaced with a local storage system (new storage system), use SmartVirtualization to manage the service LUNs in the heterogeneous storage system and leverage SmartMigration to migrate data from the service LUNs in the heterogeneous storage system to the local storage system. In this way, the local storage system carries services originally running on the heterogeneous storage system.

Procedure for configuring data migration:
  1. Install and deploy the storage systems.

    Ensure that the physical connection between the local storage system and heterogeneous storage system is correct.

  2. Configure the heterogeneous storage system.

    Map the service LUNs from the heterogeneous storage system to the local storage system.

  3. Configure the local storage system.

    Create eDevLUNs to host the service LUNs in the heterogeneous storage system.

  4. Configure SmartMigration.

    Configure SmartMigration for the local storage system and migrate cold data from the heterogeneous storage system to the local system. In this process, the source LUN is the eDevLUN (in the local storage system) that is hosted by the service LUN in the original storage system. The target LUN is the LUN that is created in the new storage system.
