Legacy systems are inflexible to change, but are tolerated due to their hard-won dependability. Migration of a legacy system to contemporary technologies is frequently postponed for fear of losing its associated reliability. When commercial pressures for change become too great, a 'one-shot' replacement effort is often undertaken very late and under severe time constraints with the anticipated consequences in quality, reliability, and user confidence. We believe that on-shot migration must be abandoned, assuming in its place a practice of controlled evolution. This project will develop a range of patterns to support evolutionary migration: domain-specific patterns of captured business process logic; patterns characterising migration processes; domain-independent patterns of component-based architectures that will be the target of migration. We will adopt a mixed approach to 'min' existing legacy systems for business process logic, where reverse and forward engineering techniques are used together, guided by business domain experts; and a component-oriented approach to migration, where we will seek to identify various roles played by a specific legacy system, permitting the evolution of those roles to component technology on a one-by-one basis. All patterns will be documented by using precise, expressive, accessible and automatable visual notations, which incorporate emerging standards.
