方式一 简单代码迁移
简单代码迁移，顾名思义，就是只迁移代码到新的地址，代码在新的地址开不了之前的提交记录。
1、登录原Gitlab页面，选择要迁移的项目，复制地址
2、使用git小乌龟克隆项目到本地
3、拉却需要的分支出来
4、登录新的Gitlab页面，创建同名的项目
创建项目方式参考：https://www.cnblogs.com/HJ-study/p/13307392.html
5、克隆新地址的项目到本地并拉取分支
6、把旧项目名目录下的的代码复制到新项目名目录下
7、进入到新项目名目录下，提交代码并推送。
方式二 Gitlab（整个项目）全库迁移
用命令行实现Gitlab上某个项目的全库迁移，包括该项目的各个分支、提交记录以及标签。
1、首先登录到新地址的Gitlab页面，新建一个项目（创建项目方式参考：https://www.cnblogs.com/HJ-study/p/13307392.html），这时新建的项目是没有分支的，如图
2、点击Git Bash Here 使用命令把旧地址的项目克隆到本地
命令如下：
1 git clone http://*.*.*.*/path/项目名称.git #旧项目仓库地址
2 cd 项目名称/
3 git branch 4 git branch -r | grep -v '\->' | while read remote; do git branch --track "${remote#origin/}" "$remote";done
5 git fetch --all 6 git fetch --tags
执行结果如下：
usrname@DESKTOP-C425NA9 MINGW64 /d/.zidingyi/move-projects $ ls #列出当前路径下文件 usrname@DESKTOP-C425NA9 MINGW64 /d/.zidingyi/move-projects $ pwd #查看当前路径 /d/.zidingyi/move-projects usrname@DESKTOP-C425NA9 MINGW64 /d/.zidingyi/move-projects $ git clone http://10.10.2.66/zeus/sandbox.git #把远程仓库的项目克隆到本地 Cloning into 'sandbox'... remote: Counting objects: 252, done. remote: Compressing objects: 100% (152/152), done.

Branch 'dev_1.4.0' set up to track remote branch 'dev_1.4.0' from 'origin'. Branch 'develop' set up to track remote branch 'develop' from 'origin'. fatal: A branch named 'master' already exists. usrname@DESKTOP-C425NA9 MINGW64 /d/.zidingyi/move-projects/sandbox (master) $ git branch #再次查看本地分支，可以看到本地已切出全部分支 dev dev_1.0.0 dev_1.1.0 dev_1.4.0 develop * master usrname@DESKTOP-C425NA9 MINGW64 /d/.zidingyi/move-projects/sandbox (master) $ git fetch --all #获取该项目远程库的所有分支及其内容 Fetching origin usrname@DESKTOP-C425NA9 MINGW64 /d/.zidingyi/move-projects/sandbox (master) $ git fetch --tags #获取该项目远程库的标签 usrname@DESKTOP-C425NA9 MINGW64 /d/.zidingyi/move-projects/sandbox (master) $ ls pom.xml README.md sandbox-batch/ sandbox-service-api/ src/
3、把本地整个项目打包压缩，移到需要的路径下面，（也可以在当前路径直接提交代码到新地址）
4、点击Git Bash Here 使用命令把代码提交到远程Gitlab库
命令如下：
1 git remote rename origin old-origin 2 git remote add origin http://*.*.*.*/path/项目名称.git #项目的新仓库地址
3 git push origin --all 4 git push --tags
执行结果：
user@▒ҿ▒▒▒▒▒▒▒▒▒▒▒▒ MINGW64 /d/old-origin/move-test $ ls sandbox/ user@▒ҿ▒▒▒▒▒▒▒▒▒▒▒▒ MINGW64 /d/old-origin/move-test $ cd sandbox/ user@▒ҿ▒▒▒▒▒▒▒▒▒▒▒▒ MINGW64 /d/old-origin/move-test/sandbox (master) $ ls pom.xml README.md sandbox/ sandbox-batch/ sandbox-service-api/ src/ user@▒ҿ▒▒▒▒▒▒▒▒▒▒▒▒ MINGW64 /d/old-origin/move-test/sandbox (master) $ git branch dev dev_1.0.0 dev_1.1.0 dev_1.4.0 develop * master user@▒ҿ▒▒▒▒▒▒▒▒▒▒▒▒ MINGW64 /d/old-origin/move-test/sandbox (master) $ git remote rename origin old-origin #将原来的origin重命名一下 user@▒ҿ▒▒▒▒▒▒▒▒▒▒▒▒ MINGW64 /d/old-origin/move-test/sandbox (master) $ git remote add origin http://110.110.2.10:8010/zeus/sandbox.git #指定需要迁移到的目标地址 user@▒ҿ▒▒▒▒▒▒▒▒▒▒▒▒ MINGW64 /d/old-origin/move-test/sandbox (master) $ git push origin --all #推送所有分支及其内容 Enumerating objects: 251, done. Counting objects: 100% (251/251), done. Delta compression using up to 4 threads Compressing objects: 100% (142/142), done. Writing objects: 100% (251/251), 2.61 MiB | 19.25 MiB/s, done. Total 251 (delta 34), reused 251 (delta 34), pack-reused 0 remote: Resolving deltas: 100% (34/34), done. To http://110.110.2.10:8010/zeus/sandbox.git

* [new branch] master -> master
user@▒ҿ▒▒▒▒▒▒▒▒▒▒▒▒ MINGW64 /d/old-origin/move-test/sandbox (master)
$ git push --tags #推送标签
5、刷新（新地址）Gitlab页面，就可以看到之前的所有分支等信息
方式三 迁移需要的分支
用命令行实现Gitlab上某个项目的的某个（某几个）分支的全部内容的迁移，具体步骤与方式二相似；参考一路追寻的博客：https://blog.csdn.net/u013938484/article/details/99541620
1、命令如下：
1 git clone http://*.*.*.*/path/项目名称.git #项目的旧仓库地址
2 cd 项目名称/
3 git branch 4 git checkout 分支名 5 git fetch --all 6 git fetch --tags 7 git remote rename origin old-origin 8 git remote add origin http://*.*.*.*/path/项目名称.git #项目的新仓库地址
9 git checkout 分支名 10 git push origin --all 11 git push --tags
2、执行结果如下：
克隆旧地址的项目到本地，切出需要的分支：

3、登录Gitlab页面检查所需要的分支是否已经提交
