Windows NT 4.0 Server Upgrade Guide 126

An accurate setup of the ADC is crucial to a successful upgrade from Exchange 5.5. ADC

provides a collection of wizards and tools that help set up connection agreements by scanning the

current Active Directory and Exchange 5.5 Directory and organization, and then automatically

creating the recommended connection agreements. This tool is a tremendous asset to the

Exchange 5.5 administrator undertaking an upgrade to Exchange 2003.

Upgrade Documentation

The documentation provided with the deployment tools package has been improved as well.

Earlier editions of Exchange (including Exchange 2000) provided very few upgrade tools, and the

documentation for the tools that did exist sometimes lacked detail. Microsoft has committed to

making upgrades from Exchange 5.5 to Exchange 2003 as simple and robust as possible—

another reason to consider upgrading directly to Exchange 2003 rather than Exchange 2000.

Feature Improvements in Exchange 2003

The following table summarizes the top feature enhancements in Exchange Server 2003.

New and Improved Features in Exchange Server 2003

Option Description

Outlook Web

Access (OWA)

The latest OWA interface looks more like the new Microsoft Office Outlook 2003

client and so provides users with a consistent experience whether in the office or

on the road. Security and performance are improved as well, and spell checking,

task scheduling, and anti-spam features have been added.

Outlook 2003 Outlook 2003 is optimized for use with Exchange 2003. A new interface

streamlines access to personal folders and displays currently open e-mail

messages. Using Exchange 2003 and Outlook 2003 in combination enhances the

performance of the Outlook client over low bandwidth and unreliable WAN links so

that remote Outlook users have a similar experience to users on a LAN. This

benefit enables remote users in small offices to use a remote Exchange server

rather than requiring a local Exchange server for performance reasons.

Mobile Access and

Synchronization

Exchange 2003 offers support and communications for an expanded set of mobile

devices. Support for iMode, cHTML, and WAP 2.0 micro-browsers enable users to

access their e-mail using the latest handheld technology, such as personal display

appliances (PDAs) and cell phones. Support is also provided for Short Message

Service (SMS) that can alert always-on mobile devices when a new message

arrives in the inbox. User can then synchronize the messages, if necessary.

Server

consolidation

Exchange 2003 builds on the server consolidation features of Exchange 2000 and

improves the use of server and storage resources by supporting the following:

§ Windows Server 2003 services that support Volume Shadow Copy service.

Volume Shadow Copy service enables online backup of Exchange Storage

Groups, so there's no need to take systems offline.

§ Instantaneous backup and restore, which removes one of the practical limits

to the number of users supported on a single server—the time it takes to back

up the mail storage.

§ Faster and more reliable synchronization. The client-to-server communication

protocol has been rewritten and optimized. These efficiency gains help to
