Git倉庫完全遷移，包括所有的分支和標簽，當然也包括日志

一、刪除原有遠程倉庫地址

git remote rm origin

二、添加新的倉庫地址

cd existing_repo
git remote add origin <URL>

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

三、遷移

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
