Legacy systems migration in CELLEST

Most research on legacy user interface migration has adopted code understanding as the means for system modeling and reverse engineering. The methodological assumption underlying the CELLEST project is that the purpose of system migration is to enable, and possibly optimize, its current uses on a new platform. This is why CELLEST uses traces of the system-user interaction to reverse engineer the legacy interface, extract its current uses and generate GUIs on new platforms as wrappers for it.
