Git仓库完全迁移，包括所有的分支和标签，当然也包括日志

一、删除原有远程仓库地址

git remote rm origin

二、添加新的仓库地址

cd existing_repo
git remote add origin <URL>

git push -u origin --all 
git push -u origin --tags

三、迁移

git clone --mirror <URL to my OLD repo location>
cd <New directory where your OLD repo was cloned>
git remote set-url origin <URL to my NEW repo location>
git push -f origin
