The paper presents a tool-supported approach to legacy data-intensive systems migration. It particularly elaborates on the program conversion phase, for which the use of wrapping techniques is suggested. The approach is applied to a popular specific application, that is, the migration of a large COBOL system using a CODASYL database towards a relational database platform. The use of the methodology and tools is evaluated in the context of a real-size industrial migration project.
