The easiest way to move a repo from one place to another including all branches ;)

Move a git repo with all its branches

# Do the usual clone of a repository
git clone <repo>

# Create local branches from remote and track them
for remote in `git branch -r | grep -v /HEAD`; do git checkout --track $remote ; done

# Set the new repo
git remote set-url origin <new-repo>

# Push everything to the new repo
git push --all
