Incremental Modernization of Legacy Systems

Abstract

This report shows an objective technique for developing an incremental code-migration strategy for large legacy Common Business-Oriented Language (COBOL) systems Specifically it describes a case study that involves the modernization of a large Supply System (55) The system consists of approximately 2 million lines of COBOL code operating in a mainframe environment The SEI developed the System Analysis and Migration (SAM) tool to generate a code migration strategy based upon legacy system analysis data SAM considers a set of factors that includes minimizing scaffolding code (code that is discarded before the completion of the project) balancing iterations and grouping related functionality
