Various systems, processes, products, and techniques may be used to manage legacy data. In one general implementation, a system, process, and/or product for managing legacy data may include the ability to determine whether a data request has been received and, if a data request has been received, determine whether the data request is associated with legacy data of an external storage management system. If the data request is not associated with legacy data of an external storage management system, the system, process, and/or product may retrieve data from a local storage array, and if the data request is associated with legacy data of an external storage management system, the system, process, and/or product may request legacy data from an external storage management system. The system, process, and/or product may also generate a response to the data request.
