Abstract. Many organizations face the problem of improving the value of their legacy systems. Modernizing the architecture of old software helps to gain control over maintenance cost, to improve system performance, and it supports moving to a distributed or more efficient environment. We propose a re-architecturing of old procedural software to an object-oriented architecture. To overcome limits of classical reverse engineering approaches building exclusively on information extractable from source code we integrate domain knowledge in the process. The resulting object-oriented software helps reduce future maintenance cost, since modern (and more calculable) maintenance technology can then be applied. In this paper, we point out the basic concepts of the re-architecturing process, the generation of design documents at different levels of abstraction, and the necessary syntactic adaptations of the source code. 1, |
