If you use Response.Redirect to direct users to a new location, you should be aware that it issues a status code of 302, which means that “the resource resides temporarily under a different URI.” If you intend to communicate that the resource has permanently changed locations, you should not use Response.Redirect. This is important for search engines and other crawlers that might need to know the definitive url.
To send a 301 redirect:
Response.Status = "301 Moved Permanently";
Response.StatusCode = 301;
Update: ASP.Net 4.0 ads a Response.RedirectPermanent() method.

This is especially important if you don’t want to lose data during the time it takes to migrate the blog, as the script can be run immediately before the switch. This script also includes additional stuff like IP addresses and url-friendly names.
