The easiest way to “move a git repository” is to clone the repository:
git clone http://github.com/foo.git
Edit the file foo/.git/config. Remove the following:
[remote "origin"] url = https://github.com/foo.git fetch = +refs/heads/*:refs/remotes/origin/*
Change “back a directory” ../
Import the repository:
git remote add origin https://github.com/my-new-repo.git git push -u origin master
This has the advantage of retaining the commit history from the previous repository.
