1- rename local branch if you are on the branch git branch -m branch-name-name

2- if you are on the different branch git branch -m branch-old-name branch-new-name

3- to delete old branch name and replace it with new name to origin git push origin :branch-old-name branch-new-name

4- step 3 will do the trick however, if you want to reset your upstream branch for new branch git push origin -u branch-new-name

Usefull tip find first commit in a specific branch git log <source_branch>..<feature_branch> --oneline | tail -1 for instance

git log master..feature/tree-shakable-components  --oneline | tail -1
