Architecture-Centric Software Migration of Web-based Information Systems

This paper presents architecture-centric software migration, an approach to improving a web-based information system. Its goal is the conversion of a web-based information system to one that is implemented in a different programming language. In order to reduce risks and the complexity of the process, it is an agile and evolutionary approach in which only small parts of the web-based information system are changed at once. Thus, while being migrated, the web information system can undergo regular further development for meeting the requirements of the web users. In addition to a detailed description of the approach, two migration strategies are introduced und
