Organizations have many options available for using improvements in new hardware, software and services to either speed legacy applications, save money, or both. One common strategy is to wrapper Web interfaces around existing legacy applications and maintain the existing legacy applications on the mainframe, while also making it possible to build applications that connect to the mainframe with Web services.

In this SearchSOA.com tip guide, readers will learn legacy application migration best practices and the important considerations when wrappering, migrating, or rewriting mainframe applications. Learn why before rewriting or service-enabling a mainframe application, you should consider the application's lifetime, how well it supports the current business needs and how easy it would be to modify the application for future needs.
