Upgrading your skills as a developer is a part of the deal of being a "professional" these days, but often it's no picnic!  I guess if I look back over my career, I've learned a dozen or so different syntax's from COBOL to C# and many versions of syntax from Visual Basic for DOS (before there was a Visual Studio product) to Visual Basic 9.0 (Visual Studio 2008).  I know how hard it can be to go from being an "expert" to a "novice" all over again as a new version of a language comes out and in the case of Microsoft, that's every few years (as we improve the framework, tools, etc.).

Fortunately, at least with Microsoft, moving from one version of a language to a newer version is relatively simple (with the exception of moving from VB to VB.NET.  That one kicked my butt! ).  The folks who run the Microsoft ASP.NET have been so nice as to release a series of articles and videos that will help you move from ASP.NET 1.1 (Visual Studio 2003) to ASP.NET 2.0 (Visual Studio 2005) and many of these videos will apply to features of ASP.NET 3.5 (Visual Studio 2008).
