COPE, a tool based on EMF that eases the migration of models in response to an evolving metamodel. COPE explicitly records the history of the metamodel as a sequence of changes and allows to attach information of how to migrate models (which is referred to as coupled evolution). The attached information can be used to automatically migrate models to the new version of the metamodel. COPE even goes one step further and allows to reuse combinations of metamodel adaptation and model migration steps across metamodels.

Legacy systems embrace a large number of technologies, making the development of tools to cope with legacy systems evolution a tedious and time consuming task. As modernization projects face with both technologies combination and various modernization situations, model-driven approaches and tools offer the requisite abstraction level to build up mature and flexible modernization solutions. MoDisco provides an extensible framework to develop model-driven tools to support use-cases of existing software modernization :
