How do I rename both a Git local and remote branch name?
1.Start by switching to the local branch which you want to rename:
git checkout <old_name>
2. Rename the local branch by typing:
git branch -m <new_name>
3. At this point, you have renamed the local branch.
If you’ve already pushed the <old_name> branch to the remote repository ,
perform the next steps to rename the remote branch.
4. Push the <new_name> local branch and reset the upstream branch:
git push origin -u <new_name>
5. Delete the <old_name> remote branch:
git push origin --delete <old_name>
