Microsoft IIS (Internet Information Services) 6.0 Migration Tool automates several of the steps needed to move a Web site or application from IIS 4.0, IIS 5.0, or IIS 6.0 to a clean installation of IIS 6.0 running on Windows Server 2003. The tool transfers configuration data, Web site content, and application settings to a new IIS 6.0 server. Migrating applications to IIS 6.0 enables organizations to take advantage of the new fault-tolerant architecture available in IIS 6.0 and other features that increase Web server reliability, performance, and security.
