A key to successfully moving to the Internet while salvaging the past investments in centralised, mainframe-oriented software development is migrating core legacy applications towards Web-enabled, client-server architectures. This paper presents the main results and lessons learned from a migration project aimed at integrating an existing COBOL system into a Web-enabled infrastructure. The original system has been decomposed into its user-interface and server (application logic and database) components. The user interface has been migrated into a Web browser shell using Microsoft Active Server Pages (ASP) and VBScript. The server component has been wrapped with dynamic load libraries written in Microfocus Object COBOL, loaded into Microsoft Internet Information Server, and accessed by the ASP pages.
