Abstract
In one implementation, a system resource is added to a storage system, for a resource-preserving upgrade. An upgrade component is coupled to the storage system as a temporary storage system shelf. Storage drives are moved from the storage system to the upgrade component. One or more storage controllers of the upgrade component are promoted to take over data services from the storage system.
