Feature Pack Deployment Guide

CHAPTER 3

Moving Exchange Files to a
NAS System

The Feature Pack provides two tools that are used to move the databases and transaction logs for
an Exchange storage group to a Windows Storage Server computer: the Remote Storage Wizard
and the WSSExchMove.exe command-line tool. These tools perform the configuration updates
that are needed to give Microsoft Exchange Server 2003 access to the remotely stored files.

This chapter explains how Exchange databases and transaction logs are moved to Windows
Storage Server computers, and provides an overview of the remote storage tools that are used to
move the files. This chapter also includes guidelines that address specific issues involved in
creating the shares that host Exchange files on a Windows Storage Server computer and in
moving the files. For detailed instructions on how to use either remote storage tool, see Help for
Remote Storage Tools for Exchange, located on the Exchange server in
%ProgramFiles%\Windows Storage Server\Exchange\RemoteStorage.chm.
