The ARNO Project: Challenges and Experiences in a Large-Scale Industrial Software Migration Project

The following paper presents the experience gained from a large scale software migration project.It describes how the migration strategy was selected and how the project was planned. It emphasizes the importance of keeping the costs as low as possible. It then goes on to outline the methods and techniques used in the migration with special emphasis on the migration process. After that, it deals with the tools used in converting the code, migrating the data and reimplementing the job control. As with all migration projects, testing played a big role and consumed a significant part of the resources. Thus, the testing techniques and tools are given particular emphasis.The paper ends with a summary of the lessons learned from this project and how they can be applied to other similar projects.
