Specification of adaptable model migrations

This paper puts the focus on adaptable model migrations. A dedicated formalism is introduced to combine automatically-generated migrations with custom-made migrations. To illustrate this issue and the approach we suggest to address it, a prototype engine is presented. Then, the prototype is applied on a case study. The prototype processes the migration specifications that have been automatically generated and then customized. The case study consists of the reuse of a mapping tool, in order to change highlighted places. During the reuse process the migration specification is customized in order to produce different migrated models.
