It is great to see TradeMe starting to serve up .aspx pages... http://www.trademe.co.nz/Browse/Motors/Cars.aspx or http://www.trademe.co.nz/Browse/Listing.aspx?id=44940798. TradeMe is the last of their sites to come over from ASP 3.0 to .NET with http://www.findsomeone.co.nz/, http://www.oldfriends.co.nz/ and https://secure.safetrader.co.nz/ having been migrated successfully last year. *Well Done* to Rowan, Jon and the TradeMe team I know the guys are seeing their systems hum on the new platform. It looks like TradeMe will get completely converted even before we do... (http://www.microsoft.com/learning/developer/default.asp).
If you are planning your own migration check out http://msdn.microsoft.com/vbrun/ and the ASP to ASP.NET v1.x Migration Assistant also here are a couple of articles to help you out... Conversion ASP .NET 1.X to ASP .NET 2.0 and Conversion VB6 to VB2005.
