I've upgraded our dev environment to TFS 2015 RC from TFS 2013 Update 4. That went really well. Now, I want to address the build environment.
What's the process for upgrading existing build controller/agents to TFS 2015 RC? Ideally I'd like the existing machines to handle both XAML and build.vnext builds.
EDIT: According to the docs, it seems like the existing build infrastructure would not get upgraded. That's fine, I'd just like to be able to manage that agent service through the admin console. Much like you can do on the app tier.
