Prepare your Source Server to prepare for Windows SBS 2008 migration
Applies To: Windows SBS 2008
Before you begin the migration process, you should back up your Source Server. This helps protect your data from accidental loss if an unrecoverable error occurs during migration.
To back up the Source Server
Perform a virus scan of all the drives and files on the Source Server.
Perform a full backup of the Source Server. For more information about backing up Windows SBS 2003, see “Backing Up and Restoring Windows Small Business Server 2003” at the Microsoft Web site (http://go.microsoft.com/fwlink/?LinkId=27140).
Verify that the backup ran successfully. To test the integrity of the backup, select random files from your backup, restore them to an alternate location, and then confirm that the backed-up files are the same as the original files.
