Migrating applications and systems from one computing environment to another is as complex a process as any in the area of computer systems development. The migration process combines the most difficult aspects of new systems development with those of systems maintenance, and puts these areas into a tightly constrained environment that invariably parallels existing business operations. In addition to the obvious tasks of modifying computer code and control procedures, there are numerous other aspects to the migration process. As organizations begin to implement the major trends in today's information systems - client/server computing, open systems, enterprise computing, and others - the orderly transition from existing information systems into some new form becomes even more important. Systems A Complete Reference discusses the many aspects of the migration process. In addition to the many technical aspects of migration - databases, networks, system software, and other areas are discussed - the book places a great deal of emphasis on the analysis and planning process. Numerous checklists and questionnaires are included that can be directly used by the reader. Additionally, a sample migration plan is also included that can be easily adapted to fit the transition plans of nearly any organization. For anyone currently undergoing - or planning to undertake - a migration effort, regardless of the complexity, this information-packed book provides an indispensable reference of practical information.
