为了从现有的仓库创建一个新的Git仓库，通常会创建一个新的仓库，并将一个或多个分支从现有仓库推送到新的仓库。

以下步骤说明了这一点：

1. 创建一个新的存储库。它必须是裸露的为了您推它。

     $ mkdir /路径/到/ new_repo 
    $ cd / path / to / new_repo 
    $ git --bare init  

   ：确保您的新存储库可从现有存储库访问。有很多方法可以做到这一点;假设您通过 ssh：// my_host / new_repo 来访问它。 推送a从现有的存储库分支。例如，假设我们希望从现有存储库中推送分支 topic1 ，并在新存储库中将其命名为 master 。

     $ cd / path / to / existing_repo 
    $ git push ssh：// my_host / new_repo + topic1：master  

这项技术可让您保留现有分支的历史记录。

I have a remote git repository that really replaced everything we had in another older SCM. Many projects and products have been added to the repository over the years.

There is a branch in this repo, corresponding to a product that I am interested in. I want to make a brand new git repository from this branch only, not really concerned about loss of history.

Is git remote add the solution? I want for both of these repositories to be on the same server.

Thoughts?

In order to create a new Git repository from an existing repository one would typically create a new bare repository and push one or more branches from the existing to the new repository.

The following steps illustrates this:

1. Create a new repository. It must be bare in order for you to push to it.

   $ mkdir /path/to/new_repo
   $ cd /path/to/new_repo
   $ git --bare init

   Note: ensure that your new repository is accessible from the existing repository. There are many ways to do this; let's assume that you have made it accessible via ssh://my_host/new_repo.

2. Push a branch from your existing repository. For example let's say we want to push the branch topic1 from the existing repository and name it master in the new repository.

   $ cd /path/to/existing_repo
   $ git push ssh://my_host/new_repo +topic1:master

This technique allows you to keep the history from the existing branch.
