Abstract and Concrete Syntax Migration of Instance Models

In this paper, we present a solution for the TTC 2010 model
migration case study. Firstly, we present a modular approach to migrate
the instance models' abstract syntax. Secondly, the problem of
co-evolution of diagrammatical information such as icon positions and
bend points of edges is identied and a solution specic to this case
study is presented. Our solution implemented using ATL and Java.
