Towards Quality Models in Software Migration

To preserve legacy systems in continuous software development and evolution, next to redevelopment, they can be migrated to new environments and technologies. Deciding on evolution and migration strategies early, requires predicting the quality of the migrated software systems depending on applied tools. There is a need for comparable measures, estimating the inner software quality of legacy and target systems. Technically, software migration tools use a transformation-based toolchain using model-driven technologies. Therefore, quality measurement can be based on the underlying models representing input and output of applied migration tools. This paper proposes a Software Migration Quality Model in order to provide support for quality-driven tailoring of utilized model-driven migration tools.
