For any server that you are thinking is a candidate for a SBS 2003 to SBS 2011 migration, next time you are doing maintenance, download two things as these are prereq’s for migration to SBS 2011 standard.
1. Powershell from http://go.microsoft.com/fwlink/?LinkID=188528
2. Microsoft Baseline Configuration Analyzer 2.0 from http://go.microsoft.com/fwlink/?LinkID=188529
You’ll need them both as part of the migration from SBS 2003 to SBS 2011
That said I should warn you that installing these puts a new section in the monitoring email. Not to worry though.
