Version control systems like Git are essential for maintaining project integrity. Making a clean break mightbe necessary for a variety of reasons. This article explains the steps necessary for creating a new Git repository from an existing one. Exploring methods for pushing a branch from the existing repository, as well as an alternative approach that bypasses Git's history preservation.

TL:DR – The creation of a new Git repository can be achieved either through direct branch transfer from an existing repository or by manually setting up a fresh project repository after decoupling it from its history. The former is preferable when history matters, while the latter might be suitable for ephemeral projects or for those that do not require access to historical data.
Understanding Git repositories
Git repositories serve as vital tools for software development by facilitating collaborative efforts among developers. A repository can either be local, residing on a developer’s machine, or remote, hosted on platforms like GitHub or GitLab. When transitioning from older version control systems, one might find their existing repository laden with an assortment of projects—sometimes convoluting the initial intention of the original project. In such scenarios, the need arises to streamline or segment these projects by creating new repositories.
Branches in Git enable parallel development. By using branches, developers can experiment or develop features independently without affecting the main project. Consequently, identifying which branch to push when creating a new repository is critical.
Finally, the process of creating a new Git repository, whether from scratch or from an existing repository, involves understanding both the basic and advanced commands in Git. Mastery of these commands is fundamental for any developer aiming to manage their code effectively.
Creating a new repository by pushing a branch
The first method involves creating a new repository that is accessible from your existing repository. This assumes a remote is available and configured correctly. For example, assume the new bare repository is located at ssh://my_host/new_repo. The steps to follow are fairly straightforward. First, ensure your remote repository is correctly set up and the necessary permissions are in place.
Next, identify the branch you wish to push from your existing repository. For demonstration purposes, let's say you have a branch called topic1 that you want to push to this new repository and designate it as the main branch. This stage does not require any elaborate setups; simply executing the command to push to your new remote will do:
git push ssh://my_host/new_repo topic1:main
Upon execution, you will have effectively transferred the specified branch from your existing repository to the new one, while retaining a clean slate on the new repository for your developmental exigencies.
Cloning the new repository
After successfully pushing your branch, the next step is to work with your newly minted repository. You can clone the new repository into a designated local working directory. In this case, let's denote the directory as new_repo. The command to achieve this is simple yet effective:
git clone ssh://my_host/new_repo new_repo
This results in a local copy of your repository, and upon inspection, you will find that the main branch of your new repository is now a faithful representation of the previously pushed topic1 branch. This method ensures that you maintain a concise history without unnecessary baggage.
Manually creating a new repository
If retaining history is of no concern, the creation of a new repository can be accomplished with greater liberty. Start by checking out the branch that captures the specific changes you wish to keep. In this instance, assume your targeted branch is mybranch. Checkout to this branch using:
git checkout mybranch
Subsequently, copy the directory contents to a new location. This can either be through terminal commands or simply employing drag-and-drop functionality in your file explorer. Upon completing this transfer, remove the .git folder contained within the copied directory. This essential step disassociates your working directory from its previous version history.
Afterward, initialise a new repository in this clean directory through the following command:
git init
Finalizing the new repository
Once the repository has been initiated, proceed to stage the files you just copied over by using the command:
git add .
Next, it is vital to configure your remote repository. This can be executed with:
git remote add origin NEW_REPO/URL
With the remote successfully added, you can create a branch name that resonates with your current development. With this in mind, renaming the branch to branch_name could be done through:
git branch -M branch_name
Finally, pushing this newly created branch to the remote repository is a simple matter of executing:
git push --set-upstream origin branch_name
Considerations for repository creation on remote servers
In instances where the computing environment necessitates creation on a remote server, simply initialising the repository with git init may be insufficient. Adopting the previously outlined methods of pushing branches or manually copying and setting up as described ensures that your new repository maintains best practices in version management while harnessing the benefits of a clean project slate.
Entering a crowded field of project management necessitates one to strike a balance between history and simplicity. Also, with remote hosting platforms gaining traction day by day, considering the nature of your projects becomes paramount for successful outcomes.
In conclusion, the processes of creating a new Git repository hinge on several factors, chiefly concerning whether to retain version history or not. Each method has its merits and may suit varying project requirements. By staying attuned to these methods, developers can streamline their workflows and maintain efficient project management.
Conclusion
To sum up, creating a new Git repository from an existing one can be conducted in a few different ways: by pushing a branch from an old repo while maintaining the history, or by bypassing these historical ties to set up a fresh repository. The former method is generally favoured for projects that depend on historical context, whilst the latter suits situations where an ephemeral or entirely fresh start is needed. In executing these steps, one can ensure the project remains orderly and manageable in its development.
For those preparing to populate a new repository, take the time to determine which method aligns best with your project needs. Familiarise yourself with the necessary commands and establish a workflow that optimises your team's productivity. It is only through proper management and a keen understanding of your tools that you can truly excel in today's software development landscape.
