Exchange Server 2003 servers meet the requirements that are described

in this section

Hardware Requirements

The following are the minimum hardware requirements for

Exchange 2003 servers:

 Intel Pentium or compatible 133 megahertz (MHz) or faster processor

 256 megabytes (MB) of RAM recommended minimum, 128 MB

 Windows 2000 SP3 or later

Note:

Windows 2000 SP3 or later is available for download at the following article: Windows 2000 Service Packs Windows 2000 SP3 or later is

also a prerequisite for running the Exchange 2003 Active Directory

Connector

 Windows Server 2003

Exchange 2000 Server Requirements

Before you upgrade your Exchange 2000 servers to Exchange Server

2003, your servers must be running Exchange 2000 SP3 or later

Exchange 2000 SP3 is available for download at the following article: Service Pack 3 for Exchange 2000 Server and Exchange 2000 Server Enterprise Edition

Windows 2000 Components

When upgrading to Exchange Server 2003, the current state of the Post Office Protocol version 3 (POP3), Internet Message Access Protocol

version 4 (IMAP4), and Network News Transfer Protocol (NNTP) services

is preserved Furthermore, if you are upgrading to Exchange Server 2003

on a server running Windows 2000, Exchange Setup installs and enables the Microsoft NET Framework and ASP.NET components automatically, which are prerequisites for Exchange Server 2003

Important:

Unless it is necessary that you run a particular service, you should

disable it For example, if you do not use POP3, IMAP4, or NNTP, you should disable these services on all of your Exchange Server 2003

servers after you install Exchange Server 2003

For more information about installing these components, see

Windows 2000 Help

Upgrading Front-End and Back-End Servers

Exchange Server 2003 supports the deployment of Exchange in a

manner that distributes server tasks among front-end and back-end

servers Specifically, a front-end server accepts requests from POP3, IMAP4, and RPC/HTTP clients, and proxies them to the appropriate

back-end server for processing

If your Exchange 2000 organization takes advantage of front-end and back-end architecture, you must upgrade your front-end servers before you upgrade your back-end servers

For more information about front-end and back-end architecture, see Configuring Exchange 2003 for Client Access

For information about front-end and back-end scenarios, configurations, and installation, see the following guides:

Back-End Server Topology Guide

for the upgrade process This section provides recommended and

required pre-upgrade procedures

Upgrading the Operating Systems

If you plan to upgrade your Exchange 2000 Servers running

Windows 2000 SP3 (or later) to Windows Server 2003, you must first upgrade those servers to Exchange Server 2003 This upgrade sequence

Note:

If you want to retain these components, do not upgrade the

Exchange 2000 Servers that are running them Instead, install

Exchange Server 2003 on other servers in your organization

Upgrading International Versions of Exchange

When upgrading from Exchange 2000 Server to Exchange Server 2003, you must upgrade to the same language version of Exchange Server
