After trying out the free Visual Studio Online you started liking it. It might so happen that the Visual Studio Online has sent you an email that the early adopter program is ending soon. So you want to move your work to TFS on-premises where you have more control and the domain integration. Here is the step by step guidance
I just saw your post about migrating VSOnline to TFS, the data export is a CSS orchestrated process =)It's not a feature (yet)
Users can find all the details about data export at msdn.microsoft.com/.../7cb80f0d-0119-4277-82e8-719a8db1796e
Also, let me highlight that the fact that early adoption is close to an end doesn’t mean that anyone has to move from the service =)
Every VSOnline account includes 5 free users and other ongoing monthly free resources (build & test).
We created these posts to add more context
