This chapter discusses changes to Adaptive Server system administration that can cause problems if you are not prepared for them. It does not attempt to cover new features or changes that are not likely to cause surprises. For a comprehensive listing of changes and new features, see What’s New in Adaptive Server Enterprise. For changes that primarily affect existing applications, see Chapter 5, “Implement: Making Required Application Changes”.
Changing applications and system administration is the most time-consuming part of migration preparation and this guide does not tell you how to make these changes. You must choose a method to do this that suits your needs and resources. For instance, you may wish to develop your own plans and scripts, or you may prefer to contact Sybase Consulting for help. Sybase Technical Support offers a Web site, the ASE Migration Resources Web page, for migration information and can help with technical problems such as bugs and error conditions.
