web site deployment issue

Question

Hello everyone,

I am deploying an ASP.Net web site, and there are related configurations, pages and binaries. There is also a related application pool related to this web site.

My question is, what is the graceful way to upgrade to an existing such type of web site? Drop the previous web site and install a new one? Any documetns or samples to make reference about how to write scripts to do such assignment automatically?

thanks in advance,
George
