Abstract
A migration object selection method selects data objects for migration from a source storage device to a target storage device. At a scheduled migration date, the method computes a benefit of migration for a selected data object based on adjustable weighted migration properties. If the benefit exceeds a predetermined threshold, the selected data object is migrated. Otherwise, the selected data object is not migrated. The weighted migration properties comprise last reference date, data object size, version, format, access speed of the source storage device, access speed of the target storage device, speed of a network, and location of the source storage device. The weighted migration properties are weighted with an adjustable weighting factor that indicates a relative importance of each of the weighted migration properties.
