1.1. The Exchange 2000 Upgrade Series

Welcome to the Microsoft^® Exchange 2000 Server Upgrade Series. This guide is designed to give you—the Exchange 2000 system architect, consultant, or system integrator—the best information available about upgrading from Microsoft Exchange Server 5.5 running on the Microsoft Windows NT^® 4.0 operating system to Exchange 2000 running on the Microsoft Windows^® 2000 operating system. Sections of this guide cover upgrading the core messaging services such as mailboxes, calendar, address book as well as migrating public folders, connectors, and other components. Other sections include advanced messaging capabilities, such as Microsoft Outlook^® Web Access, front-end/back-end servers and advanced security.

Within these chapters, we have taken pains to pass on information that is both practical and prescriptive. We have incorporated material from consultants working in the field that represents what is currently defined as "best practice." Step-by-step procedures give you a list of tasks to perform to move from where you are to where you want to be. We have also included hints and tips about procedures covering both Exchange 2000 and Windows 2000 Active Directory.
