If you configured the new storage subsystem with at least two new drives
to get the storage subsystem into Optimal state for updating the controller
firmware, perform one of the following tasks:

Leave the new storage subsystem configuration as is. Perform steps 4c-4g,
5a or 5b, and 5c-5e to prepare the original subsystem configuration for
drive and drive enclosure migration and to turn off power of the original
storage subsystem. Use the procedure in Chapter 3, “Adding or migrating
storage enclosures,” on page 25 to migrate the drives and storage
enclosures in the original storage subsystem into the new storage
subsystem configuration. After you migrate all of the drives and storage
