Migrating a Web Server to IIS 5.0

Replicating and Configuring Applications

Application files are a special case. Rather than copying them directly to the new IIS 5.0 server, application files should be transferred to a development computer for any necessary editing or rewriting, and then to a test computer for testing and debugging. When you’re ready to deploy the application on the new IIS 5.0 server, follow the instructions given in the “Configuring Applications” topic of the IIS 5.0 online product documentation.

Later in this section, Migrating Web Applications describes your options for migrating a CGI application to IIS 5.0. You can leave it as a CGI and make relatively minor changes so it runs on IIS 5.0. Or you can rewrite it as an ISAPI extension or an ASP application. The pros and cons of each approach are discussed in terms of development costs and server resources.
