Like cars that become “used” as soon as you drive off the lot, today’s software systems seem to become “legacy” almost instantaneously. IT organizations are making huge investments in rejuvenating legacy systems. But many modernization projects fail, often spectacularly. Modernizing Legacy Systems shows how to do the job right.
This book’s authors come from the Software Engineering Institute -- the center of the universe when it comes to software development processes and software quality. They’ve seen it all. And they’ve synthesized it all into lessons and techniques that encompass technology, process, and business issues.
You’ll start by comparing your options for modernization, and the issues associated with each: “white-box” modernization which messes with the internals, “black-box” modernization, which attempts to leave them alone; replacement, retargeting, user interface revamping, and so forth. Then, using a fictional “Retail Supply System” case study that draws upon dozens of actual projects, they walk through the entire modernization process.
You’ll master Risk Managed Modernization (RMM), a process for continually assessing what can go wrong, and planning in advance to mitigate those risks. You’ll then systematically address architectural transformation, language migration (in this case, from COBOL to Java/J2EE), transactional issues, and middleware (this case study uses IBM’s WebSphere MQSeries). You’ll plan for both code and data migration, estimate resource requirements, build an integrated modernization plan -- and, finally, review the high-level principles that lead to lower risk and better results.
