When Microsoft redesigned its SharePoint products, it also changed some of the terminology associated with the technology. These changes are described in the following sections. For users of SharePoint Team Services, or SharePoint Portal Server 2001, it is important to understand how the terminology has changed.
Roles from SharePoint 2001 have been replaced with site groups in SharePoint 2003. Site group names and definitions are slightly different from the SharePoint 2001 role names and definitions. When migrating from SharePoint Portal 2001 to SharePoint Portal 2003, Table 2.1 shows the site group SharePoint 2001 users will be in after the migration.
