A Novel Approach for Replacing Legacy Systems

Y. Moghaddas and H. Rashidi

Modernizing and reengineering on the legacy systems is an essential need in software industries. The replacement of legacy software systems is one of the most effective parts in process of modernizing software systems. In this study, a useful method for replacement of legacy large systems is proposed. In this method, the incremental approach is used to create interface and control layers on the corresponding sectors in two systems. With considering a new system in under-controlled condition and testing with real data and finding possible errors, replacement process faces with low risk. In comparison of proposed method with other traditional methods, two main differences are considered. In proposed method, data bases and resources of new system shall be different with legacy system. Second difference is finding errors to make final systems ready to decrease the risks and increase reliability.
