Answer by Dragomir Ivanov for Git push existing repo to a new and different remote repo server?

Well, a lot of answers. Mine will be one of the shortest. You want to push to a new server, but also to keep all the history and branches:

git clone --mirror https://git1.com/project/repo_name.git

cd repo_name

git branch

git remote set-url origin https://git2.com/project/repo_name.git

git push --mirror
