For a project I was looking for a document about migrating from Windows 2003 Small Business to Windows 2008 R2 and Exchange 2010. I’ve found a great article written by demazter, this article describes every step. Original link: http://www.experts-exchange.com/Software/Server_Software/Email_Servers/Exchange/A_2881-Migrate-Small-Business-Server-2003-to-Exchange-2010-and-Windows-2008-R2.html
This guide is intended to provide step by step instructions on how to migrate from Small Business Server 2003 to Windows 2008 R2 with Exchange 2010.
For this migration to work you will need the following software:
- Windows Small Business Server 2003 (SBS 2003)
- Windows 2008 Server or Windows 2008 R2 Server
- Exchange Server 2010
- Microsoft Office Filter Pack from here: http://www.microsoft.com/downloads/details.aspx?FamilyID=60c92a37-719c-4077-b5c6-cac34f4227cc&displaylang=en
- Windows SharePoint Services 3.0 with integrated Service Pack 2.Only the version with Integrated Service Pack 2 will install on Windows 2008 R2. You can download it from here: http://www.microsoft.com/downloads/details.aspx?familyid=9FB41E51-CB03-4B47-B89A-396786492CBA&displaylang=en
- Microsoft SQL Server Management Studio Express which can be downloaded from: http://www.microsoft.com/downloads/details.aspx?FamilyID=c243a5ae-4bd1-4e3d-94b8-5a0f62bf7796&displaylang=en You will need to download both the 32bit and 64bit versions
Steps required:
- 1. Health Checks on Small Business Server 2003
- 2. Join new Windows 2008 Server to the domain as a member server
- 3. Prepare Active Directory for Windows 2008 R2 Server
- 4. Make Windows 2008 R2 Server a Domain Controller of the Existing Small Business Server 2003 Domain
- 5. Transfer DHCP Service
- 6. Install Exchange 2010
- 7. Installing Exchange 2010 SSL Certificate
- 8. Migrate Exchange Data
- 9. Migrate SharePoint Services
- 10. Migrate shared user data
- 11. Uninstall Exchange 2003 from Small Business Server 2003
- 12. Transfer all 5 FSMO roles to Windows 2008 Domain Controller
- 13. DCPROMO SBS 2003 server so it is no longer a domain controller and remove from network
It’s important that the steps are followed in order as different stages make different changes to the way in which your server operates. For example you MUST make the 2008 server a domain controller before you install Exchange.
