Abstract: Banks are still using legacy systems as the core of their business is comprised within such sys-tems. Since the technology and client demands are changing rapidly, the banks have to adapt their systems in order to be competitive. The issue is to identify correctly what are the bank users preferences in terms of software reliability and how modern is the system For instance, there are users who enjoy working using the old screen format, and there are users who enjoy working with newer layouts, Web interfaces, and so on. We need also to know the constraints generated by the usage of legacy systems, and how these systems can be improved or replaced. The scope of the article is to present a solution of modernizing a legacy banking system by using a SOA approach. The research is based on the modernization of a legacy system developed in COBOL/400 under IBM iSeries. The modernization process uses a SOA ap-proach using JAVA technologies.
