One of my clients has an e-commerce CMS written in VB.NET 1.1. (The original solution was authored with Visual Studio 2003.) It's not an enormous site, but it does consist of around 40 or 50 Web forms, and I'd like to upgrade it to .NET 3.5, and to maintain and continue developing it it with VS 2008.

I's sure I could do it surgically, re-creating the new project one file at a time, testing at each step of the way, and so on, but is there an easier way? I somewhat optimistically hoped VS 2008 would offer some sort of an upgrade wizard, but no such luck for Web Site projects, it looks like.

Anyone gone through this already? If so, what would you suggest as the most sensible approach?
