Migrating Automotive Product Lines: A Case Study

Software Product Lines (SPL) are widely used to manage variability in the automotive industry. In a rapidly changing industrial environment, model transformations are necessary to aid in automating the evolution of SPLs. However, existing transformation technologies are not well-suited to handling industrial-grade variability in software artifacts. We present a case study where we "lift" a previously developed migration transformation so that it becomes applicable to realistic industrial product lines. Our experience indicates that it is both feasible and scalable to lift transformations for industrial SPLs.
