Renaming a branch in GitHub

Question

I just renamed my local branch using

git branch -m oldname newname

but this only renames the local version of the branch. How can I rename

Answer 1

Just remove the old branch and create new one.

Example (solely renaming the remote branch):

git push origin :refs/heads/oldname
git push origin newname:refs/heads/newname

You also probably should rename local branch and change settings for where to push/pull.
