1. A processor-implemented method for migrating an item within a workflow process, comprising: specifying a plurality of logical nodes within the workflow process; selectively associating a plurality of physical nodes with the logical nodes to generate the workflow process; determining whether an item requires physical migration; upon determination that the item requires physical migration, selecting a target physical node from the set physical nodes, and physically migrating the item to the physical location; and upon determination that physical migration is not required, performing logical migration to a subsequent logical node without physical migration.
