TFS Create Main and Development branch from existing team project

Question

Currently we have a team project in TFS 2010 named MyApp that was put in years ago. I would like to create MAIN and DEV branches as described in the ALM Rangers guide. I know it would've been easier if the existing team project was created with the branches initially, but that's in the past. I don't want to lose the version history in the existing project.

Is it possible to create those branches (or at least a DEV branch) without affecting the existing project?

UPDATE My folder structure looks something like this (bold is folder, italic is file):

• server\DefaultCollection
  • MyApp
    • Lib
    • packages
    • Repositories
    • MVCClient
    • MyApp.sln

There's not a great solution to this, but here's one option:

Create a MAIN folder. Copy all your source under this folder. Convert MAIN to a branch. Branch DEV from MAIN.

Keep your old source code around (the stuff not under the MAIN folder) for history purposes.
