We are thinking of moving from BTDF to the new VSTS automatic deployment mechanism.

In my test setup, deploying to a single node BTS server worked just fine, but I wonder how it is done having a BizTalk group with multiple servers.
In BTDF the .msi's needed to be run on all nodes (once with 'this is the first server in the group' checked) in order to once create the application and on the other nodes to just install and GAC resources...

Is this being done automatically by the 'Deploy BizTalk Server Application' deployment task or do I have to run it once with 'Create new BizTalk Server application' and on the other servers with 'Install BizTalk Server Application' set?

If yes, do I simply run it on the deployment agent of the node with the management db or would I deploy to a deployment group/environment resource group containing all nodes?
