Applies To: Windows Server 2003, Windows Server 2003 with SP1

Before upgrading your existing server running IIS, ensure that Windows Server 2003 supports all of the hardware devices that are on the server. You must also ensure that your Web sites and applications are compatible with IIS 6.0, Windows Server 2003, and worker process isolation mode. Lastly, you must determine whether any of your existing ASP.NET applications are compatible with version 1.1 of the .NET Framework that is installed with Windows Server 2003.

Figure 5.2 illustrates the process for preparing to upgrade an IIS server to IIS 6.0.
