If you are using Visual Studio for your development there is an upgrade feature that takes care of quite a few things.

As @Development4.0 suggested, you could open the 1.1 sln file in VS2008 and go through the wizards. If you have multiple projects (like Web Projects, Class Library etc), then I would suggest a step-by-step approach. There will be breaking changes for sure, but I think would be minimal.
