Change a subfolder in git repository to be a new repository while keeping history

Question

I have a project named Project_A which contains a folder Pro_A which is used by Project_B as a submodule. I would like to make Pro_A a standalone project and have both Project_A and Project_B to use it as a submodule. Is there a way to do this while preserving history for Pro_A

Answer 1

One way to maintain the history is to clone the original repo, then delete the folders you don't want and commit it. Similarly, you can delete the folders from the original repo that you want in the new repo.
