I have inherited an SBS2003 Std server and preparing it migration to SBS 2011 Std usinghttp://technet.microsoft.com/en-us/library/gg563799.aspx. It talks about ensuring service packs are installed. It says that SBS2003 sp1 needs to be installed before installing Server 2003 sp2 to ensure proper .NET framework is installed. Already installed on this server is SharePoint 2.0 sp3, Exchange Server 2003 sp2, and Server 2003 sp2. There is no listing in add/remove programs for SBS2003 sp1 and if I do Winver all I get is a listing for v5.2 build 3790srv03_sp2. I did a registry search for the KB # associated with SBS2003 sp1 (885918) and found nothing.
Is SBS2003 sp1 listed somewhere else or can I assume it is not installed? If it is not installed can I expect problems continuing with the preparation and migration especially since it references versions of .NET?
This migration will be to new server hardware.
