This paragraph let me sit straight up:
Previously we have released guides that describe how you can upgrade manually step by step. Moving forward we will not release these guides. Instead you should use our upgrade plan or examine changes to the code base and implement them manually on your own.As upgrade plans will not include Orckestra employees travelling around to update TFS based Visual Studio solutions our only option would be to develop upgrades by ourselves. Guess it is time to remove Composite C1 from my newest project.
