Renaming a local and remote branch in git

If you have named a branch incorrectly AND pushed this to the remote repository follow these steps to name them properly

1. Rename your local branch.
If you are on the branch you want to rename:

1
git branch -m new-name

If you are on a different branch:

2
git branch -m old-name new-name

2. Delete the old-name remote branch and push the new-name local branch.

3
git push origin :old-name new-name

3. Reset the upstream branch for the new-name local branch.
Switch to the branch and then:

4
git push origin -u new-name

 

Cheers!
