Eli Ofek has published a 5-part (well, 4-part really) series about migrating an actual project from the classic triad of VS2003/.NET 1.1/VSS to VS2005/.NET 2.0/Team Foundation Server. I used to be a developer on the "sister team" of the project he's talking about, and I can tell you that it's a huge project with an extremely talented and devoted team of developers, so if you're going to be doing any migration work in the nearby future I highly recommend you go ahead and do some serious reading on his blog. The bottom line is that Beta 2 servers aren't stable enough, nor the IDE performant enough, to do any proper work on. The little experience I had with the VS2005 was that it was actually very good and the performance just fine (on my 1.7GHz Dothan laptop w/1GB memory), but I can't argue with server stability issues.

Regardless, I particularly recommend reading phase 3, which discusses critical language/library differences.

• Phase 1 (continued): Installing the environment
• Phase 2: Migrating VSS 6.0d to Team Foundation
• Phase 3: Migrating the code from 1.1 to 2.0
• Phase 4, 5: Pilot cancellation
