Migrating IIS Web Sites to IIS 6.0
You can move Web sites and applications to Internet Information Services (IIS) 6.0 in two ways. Migrating is installing the Microsoft® Windows® Server 2003 operating system and IIS 6.0 on a new server and then moving, or reinstalling, existing Web sites and applications to that server. Upgrading is installing Windows Server 2003 and IIS 6.0 on an existing server running the Microsoft Windows NT® Server 4.0 operating system and IIS 4.0 or the Microsoft Windows® 2000 Server operating system and IIS 5.0. Both processes involve minimal outage of service to users who access the Web sites and applications, while retaining the majority of the original configuration settings and fully preserving the content of the Web sites and applications.
