Before You Begin
Microsoft® Exchange Server consists of services that provide your company with advanced messaging and information management tools. Before you begin migrating from your present mail system to Microsoft Exchange Server, it is important to have a plan in place. This is particularly necessary for large organizations where preparation is key to the successful implementation of a new system. You should assess your needs and resources and decide how you will distribute those resources most effectively. Making these kinds of decisions during the planning phase allows you to move to your Microsoft Exchange Server efficiently and saves you time and effort later.
This book discusses the concepts for migrating to Microsoft Exchange Server, an overview of the available tools, and instructions for moving from your existing system to Microsoft Exchange Server. Administrators are strongly advised to use this guide to plan their Microsoft Exchange Server migration.

For improved performance, you should plan your server’s hardware to meet the expected load. The hardware requirements for each computer that will be running Microsoft Exchange Server software are described in the following table. Note that Microsoft Exchange Server can take advantage of advanced hardware such as multiprocessor computers and caching disk array controllers.
