Not on MSDN yet (it's on the [great] other place), but there is now an Alpha of an ASP to ASP.NET Migration Assistant:
The ASP to ASP.NET Migration Assistant is designed to help you convert ASP pages and applications to ASP.NET. It does not make the conversion process completely automatic, but it will speed up your project by automating some of the steps required for migration.
May be just the thing to get some older, semi-cranky ASP code prepped and ready for the ASP.NET Whidbey Beta...
