If you create a new clone of the repository, you won't lose any of your Git history or changes when you split a folder into a separate repository.
Change the current working directory to the location where you want to create your new repository.
Clone the repository that contains the subfolder.
$ git clone https://hostname/USERNAME/REPOSITORY-NAME
Change the current working directory to your cloned repository.
$ cd REPOSITORY-NAME
To filter out the subfolder from the rest of the files in the repository, run
git filter-repo, supplying this information:
FOLDER-NAME: The folder within your project where you'd like to create a separate repository.
Tip: Windows users should use
/to delimit folders.
$ git filter-repo --path FOLDER-NAME1/ --path FOLDER-NAME2/ # Filter the specified branch in your directory and remove empty commits > Rewrite 48dc599c80e20527ed902928085e7861e6b3cbe6 (89/89) > Ref 'refs/heads/BRANCH-NAME' was rewritten
The repository should now only contain the files that were in your subfolder(s).
Create a new repository on GitHub Enterprise Server.
At the top of your new repository on your GitHub Enterprise Server instance's Quick Setup page, click to copy the remote repository URL.
Tip: For information on the difference between HTTPS and SSH URLs, see "About remote repositories."
Check the existing remote name for your repository. For example,
upstreamare two common choices.
$ git remote -v > origin https://hostname/USERNAME/REPOSITORY-NAME.git (fetch) > origin https://hostname/USERNAME/REPOSITORY-NAME.git (push)
Set up a new remote URL for your new repository using the existing remote name and the remote repository URL you copied in step 7.
git remote set-url origin https://hostname/USERNAME/NEW-REPOSITORY-NAME.git
Verify that the remote URL has changed with your new repository name.
$ git remote -v # Verify new remote URL > origin https://hostname/USERNAME/NEW-REPOSITORY-NAME.git (fetch) > origin https://hostname/USERNAME/NEW-REPOSITORY-NAME.git (push)
Push your changes to the new repository on GitHub Enterprise Server.
git push -u origin BRANCH-NAME
