With the progress of the software technology, the existing legacy systems are becoming obsolete and unable to satisfy the customer needs and expectations. Most of the legacy systems designed using COBOL, as it is a programming language. On the other hand, today Java widely used programming language for designing systems. The Java is pure object-oriented, where as the COBOL is procedure oriented programming language. The legacy systems designed earlier needs the huge amount of maintenance. The programmers of these legacy systems are now getting old moving into the retirement. After that, for people maintaining legacy systems it will be more difficult because keep up these legacy systems needs expertise in the programming language.
