核心

#从老gitlib拉取裸仓库，并在本地文件系统创建gitbook-demo.git文件夹
git clone --bare ssh://git@oldgitlab:port/group1/gitproject-demo.git
#进入代码目录
cd gitproject-demo.git
#向新git推送镜像
git push --mirror ssh://git@newgitlab:port/group1/gitproject-demo.git

--bare是裸仓库的意思，区别与git clone，他不是一个工作空间，不可以在目录下进行变更操作，即使操作了也不被接受，执行命令后会复制全部的分支、标签,并且在命令执行过程中的所有远端的变动均被忽略。

–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 --no-checkout 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 torefs/remotes/origin/. When this option is used, neither remote-tracking branches nor the related configuration variables are created.

--mirror镜像代码仓库，完完整整

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..mirror is set.

$ git clone --bare  http://ip:port/xxxx/yyy.git

推送bare版本到新Gitlab

```java
ysw@DESKTOP-T7NDJ0A MINGW64 /d/codeMerge
$ pwd
/d/codeMerge

ysw@DESKTOP-T7NDJ0A MINGW64 /d/codeMerge
$ cd uomSM.git/


- uom子群组名
- yyy自定义项目名称，我一般保持和旧的项目一致
$ git push --mirror https://新git地址/xxxx/uom/yyy.git
