Create a new git repository from a existing local branch

I have a Git repository with two branches: master and redesign. The redesign branch was created from master, and master has not been touched since then:

            \--m51--|--m52--|--m53-- redesign

The redesign branch has evolved so much that I would like to create a new whole repository from it, taking the first commit of redesign as the initial commit of the new repository and forgetting the previous history inherited from master:

  • Git - Where do files go when you change branches?
  • Git: Howto move changes since last commit to a new branch
  • Commit to multiple branches at the same time with git
  • How to push a new branch non-existing on the remote server without --set-upstream?
  • How to create a new source code branch using TFS API?
  • git: How to rebase all commits by one certain author into a separate branch?
  • master

    Is this possible with Git? There is a related question to this, but its goal is to use a directory, not a branch.

    You could:

    • checkout the commit you want for the “root” of your new repo
    • copy all the files to your new directory (except the .git directory)
    • check out your redesign branch
    • git format-patch master..redesign
    • move all the generated patch files somewhere handy

    Then go to your new directory and:

    $ git init
    $ git add .           # make sure your .gitignore is in place though
    $ git commit -m"..."
    $ git am /path/to/patches/*.patch

    First, copy or clone your git repository.

    Then, find out the hash of your new root commit (m51 in your diagram). Put its commit hash into the file .git/info/grafts, then run git filter-branch --all. After you have verified the successful operation, you can remove the original/* backup refs (or re-clone the repository).

    Please note that this will create new commit hashes for all commits, so you have to be careful with already published history.

    Create your new repository, then:

    $ git add remote newrepo <path to newrepo>
    $ git checkout redesign
    $ git checkout --orphan clean
    # The branch is empty, but the files from the original branch are staged for commit.
    $ git commit -m"clean"
    $ git push newrepo clean:master

    Note: If you want to preserve history (or don’t care), omit the creation of the “clean”
