Move Exchange Server mailboxes and settings for Windows SBS 2008 migration

Updated: March 3, 2009

Applies To: Windows SBS 2008

If Exchange Server is installed on the Source Server, this is a required task.

These instructions are for migrating from Windows SBS 2003. If you are migrating from Windows SBS 2008, see the Microsoft Web site (http://go.microsoft.com/fwlink/?LinkId=144389).

Before you migrate Exchange Server mailboxes and settings to the Destination Server, you should clean up the Exchange Server database and verify its integrity by doing the following:

  • Ask each user to do the following:

    • Delete unneeded mail from their mailbox, including mail in the Deleted Items and Sent Items folders.

    • Archive older mail to a .pst file, if appropriate. For more information about creating a .pst file, see Outlook Help on the client computer.

    • Review and delete unneeded personal documents from the user’s folders, the Company Shared folder, and other shared folders on the server.

  • Back up the database. For information about backing up an Exchange Server 2003 database, see "Overview of Exchange Server Backup Methods" at the Microsoft Web site (http://go.microsoft.com/fwlink/?LinkId=98934).

  • Use the Exchange Server Database Utilities to help you determine the status of the Exchange Server 2003 database. For more information, see the "Exchange Server Database Utility Guide" at the Microsoft Web site(http://go.microsoft.com/fwlink/?LinkId=98935).

If you are migrating from Windows SBS 2003 to Windows SBS 2008 with Microsoft Forefront Protection 2010 for Exchange Server (FSE) enabled, FSE starts scanning mailboxes on the Destination Server immediately after the installation finishes. If FSE detects a virus, it is removed automatically. FSE also blocks file types that have the potential to cause business impact. File types that are filtered are listed in the following table.
