So you are considering implementing Exchange 2007 into an SBS 2003 environment. This post will cover the pros and cons, it will also give a high level overview on the installation of Exchange 2007 into an existing SBS 2003 Exchange environment.
First we should address some of the common reasons people consider adding an Exchange 2007 Server into an existing SBS 2003 environment.
is a single-server solution that uses built-in asynchronous log shipping and log replay technology to create and maintain a copy of a storage group on a second set of disks that are connected to the same server as the production storage group
The major downside to installing Exchange 2007 into your SBS environments is that most of the simplicity of SBS will be gone? You will not be able to use the SBS Wizards to help configure Exchange. The CEICW will also fail. The Add User Wizard will not ask you which Exchange to create a new mailbox on, it will pick one for you. You will need to support Exchange 2007 and your existing Exchange 2003 using the Exchange tools and not the SBS tools. Another downside is that you will not get mailbox store replication. Finally your existing SBS CALs will not cover client access to the new Exchange 2007 Server, so you will have to buy Exchange licenses for your users.
Exchange 2007 will be included in the next version of Small Business Server codenamed “Cougar”. When this version of SBS is released Exchange 2007 will be fully integrated into all the SBS Wizards. We recommend that most SBS users use “Cougar” as their entry into the Exchange 2007 world. For more information on the SBS product roadmap please see:
If you have decided that you cannot wait for “Cougar” and want to implement Exchange 2007 in your current SBS environment please read on.
Exchange 2007 provides the following five distinct server roles that align to how messaging systems are typically deployed and distributed:
The easiest way to capture most of the information about your Exchange organization, Active Directory, and other settings and configuration information is to scan the organization using the
Microsoft Exchange Server Best Practices Analyzer Tool
(ExBPA). ExBPA version 2.7 and later includes an Exchange 2007 Readiness Check scan that can be used to assess your organization's readiness for Exchange 2007. As part of that assessment, the organization model is also identified.
After the Exchange 2007 Readiness Check scan is complete, a report is generated. After the report is complete, navigate to the All Issues tab and look for an entry called Transition documentation. Select this item to display the organization model for the scanned Exchange organization.
This topic explains how to prepare the Active Directory directory service and domains for installing Microsoft Exchange Server 2007. You must complete this procedure before you install Exchange 2007 on any servers in your organization.
When installing Exchange 2007 on Windows Server 2003 64bit server in SBS domain, the steps are:
Promote the Windows Server 2003 x64 server to be a DC in SBS domain
On Windows Server 2003 x64 server, install IIS, Windows 2003 Service Pack 2, Windows Powershell, .Net Framework 2.0, MMC 3.0, update 933360, and update 926776. Restart the server as you are prompted.
On the SBS Server change Exchange from mixed mode to native mode (SBS’s Exchange is defaulted in mixed mode)
On the Windows Server 2003 x64 server, find the Exchange setup root folder, type "setup /pl" and wait until it finished.
On the Windows Server 2003 x64 server, browse to the Exchange setup root folder and double click setup.exe
