Duplicate file with branches

I have a Project A in which there is a file(Default). I want a copy or duplicate of file(Default) in another Project B with all the branches(Active or Archived). How i can achieve this. Kindly guide.


I too need this. In order to approve a component update to our component library, I need to check in safe environment. I want to do this in a safe environment.

More specifically I want to duplicate the library file, then create a design file, attach the library file, add the current component to the design file, then merge the branch that contains the updated component. Then I want to update the component in my design file, and look for issues. If I find no issues, I can merge and publish the original file. Done.
