1. 需求

2. 实现

第1步：从原地址克隆一份裸版本库

git clone  --bare 解释

第2步: 以镜像推送的方式上传代码

git push --mirror 解释

--------------------

# 1. 需求 #

> Git仓库地址改变，需要代码迁移，但需要保留之前开发人员的提交记录，方便回溯

### git clone  --bare 解释 ###

> \--bare
> 
> Make a *bare* Git repository. That is, instead of creating `<directory>` and **placing the administrative files in `<directory>/.git`**, make the `<directory>` itself the `$GIT_DIR`.
> 
> This obviously implies the `-n` because there is nowhere to check out the working tree.
> 
> **Also the branch heads at the remote are copied directly to corresponding local branch heads,** without mapping them to `refs/remotes/origin/`.
> 
> When this option is used, neither remote-tracking branches nor the related configuration variables are created.

### git push --mirror 解释 ###

> \--mirror
> 
> Instead of naming each ref to push, specifies that **all refs under `refs/` (which includes but is not limited to `refs/heads/`, `refs/remotes/`, and `refs/tags/`) be mirrored to the remote repository.** 
> 
> **Newly created local refs will be pushed to the remote end**, locally updated refs will be force updated on the remote end, and deleted refs will be removed from the remote end.
> 
> **This is the default if the configuration option `remote.<remote>.mirror` is set.**
