Abstract Evolution of legacy systems: strategic and technological issues, based on a case study

The goal of this experience report is to highlight the strategic and managerial issues that are likely to be involved in any migration or evolution effort of large-scale legacy systems. The report is based on a specific case study of a large organisation in the Belgian health care and social security system. Major drivers for a legacy evolution effort are identified. Emphasis is put on the required management and planning view, rather than on the mere technological issues. Their constituent elements are discussed in some detail
