How to Rename Git Branches Locally and Remotely

To rename a Git branch both locally and remotely, you need to follow a specific sequence of commands since Git doesn’t allow direct renaming of remote branches. For your situation with the local master branch pointing to the typo’d origin/regacy, you’ll need to rename the local branch, delete the old remote branch, and push the corrected branch name.

Understanding Git Branch Renaming

Git doesn’t provide a direct command to rename remote branches. As Linuxize explains, “you can’t directly rename a remote branch; you need to push the renamed local branch and delete the branch with the old name.”

The git remote rename command you attempted is for renaming entire remote repositories (like changing the remote name from “origin” to “upstream”), not for renaming individual branches within a remote repository.

Step-by-Step Process for Renaming Branches

The standard approach involves three main steps:

1. Rename the local branch using git branch -m
2. Delete the old remote branch using git push origin --delete old-name
3. Push the new branch and set upstream using git push origin -u new-name

PhoenixNAP confirms: “There is no direct way to rename a Git branch in a remote repository. You need to delete the branch with the old name and then push a branch with the correct name to the remote repository.”

Your Specific Case: Renaming from regacy to legacy

Here’s the complete process for your situation:

Step 1: Rename the local branch

git checkout master
git branch -m master legacy

Note: The git branch -m command renames the current branch. If you’re not on the branch you want to rename, you can specify both old and new names: git branch -m old-name new-name Better Stack Community

Step 2: Delete the old remote branch

git push origin --delete regacy

This command removes the typo’d branch from the remote repository IONOS.

Step 3: Push the new branch and set upstream

git push origin -u legacy

The -u flag sets the upstream tracking for future pushes DataCamp.

Step 4: Update your local tracking

git branch --set-upstream-to=origin/legacy legacy

This ensures your local branch properly tracks the remote branch.

Alternative: Renaming to master

If you prefer to rename to master instead of legacy, follow these steps:

git checkout master
git branch -m master master  # This might seem redundant but ensures the rename
git push origin --delete regacy
git push origin -u master

Common Mistakes and Troubleshooting

Error: “fatal: ‘regacy’ does not appear to be a git repository”

This occurs when trying to delete a branch that doesn’t exist. Verify the branch name is correct using git branch -r.

Error: " ! [remote rejected] regacy (already exists)"

This happens if someone else still has the branch checked out on their local repository. Coordinate with your team before deleting.

Error: “fatal: The current branch master has no upstream branch”

Use git push origin -u master to set the upstream tracking Git Tower.

Multiple branches pointing to the same commit

If you have both master and legacy branches pointing to the same commit after renaming, you can use:

git branch -d master  # Delete the old local branch if it still exists

Best Practices

1. Communicate with your team before renaming shared branches to avoid conflicts
2. Always verify branch names before deletion using git branch -r
3. Use consistent naming conventions to avoid future typos
4. Check the remote repository after renaming to confirm the changes took effect
5. Pull the latest changes before renaming if working in a team environment

As Blackdown notes, “Failing to follow naming conventions in Git can lead to various problems, but as you can see, it’s definitely not the end of the world if you’ve made a mistake.”

Conclusion

Renaming a Git branch both locally and remotely requires a systematic approach since direct renaming isn’t possible for remote branches. The key steps are: rename locally, delete the old remote branch, and push the new branch with proper upstream tracking. For your specific case with the typo’d regacy branch, follow the three-step process outlined above to successfully rename it to legacy or master.

Remember to communicate with your team before making these changes, especially if the branch is shared among multiple developers. Always verify that the rename was successful by checking both local and remote branch listings.
