I have an NT 4.0 server we'll refer to here on out as &quot;OLD&quot; running Exchange 5.5 with just under 95MB of space on it. I have a brand new server running Windows Server 2003 R2 Std Ed. we'll refer to as &quot;SELHS02&quot;. I'd like to move all the mail duties from OLD to SELHS02 and am ready to install Exchange 2003 on SELHS02. What are the proper steps to take in this migration from beginning to end? I have a general idea of what has to happen but am apprehensive because I do not understand everything involved completely. I've heard of exmerge.exe - do I need to use that? Do I need to build a scratch box and load Server 2000 on it? Please help point me in the right direction and the first steps to take. Any help is much appreciated....

What is the correct procedure for migrating from Exchange 5.5 to Exchange 2003?

Windows Server 2003 was based on Windows XP and was released in four editions: Web, Standard, Enterprise and Datacenter. It also had derivative versions for clusters, storage and Microsoft’s Small Business Server. Important upgrades included integrating Internet Information Services (IIS), improvements to Active Directory (AD) and Group Policy (GP), and the migration to Automated System Recovery (ASR).

Windows Server 2003

Active Directory (AD) is a Microsoft brand for identity-related capabilities. In the on-premises world, Windows Server AD provides a set of identity capabilities and services, and is hugely popular (88% of Fortune 1000 and 95% of enterprises use AD). This topic includes all things Active Directory including DNS, Group Policy, DFS, troubleshooting, ADFS, and all other topics under the Microsoft AD and identity umbrella.

Active Directory

Exchange is the server side of a collaborative application product that is part of the Microsoft Server infrastructure. Exchange's major features include email, calendaring, contacts and tasks, support for mobile and web-based access to information, and support for data storage.
