7. Review Redirect and Repo Impact
   GitHub automatically sets up redirects for your repositories, but you should still update links manually wherever your old username was used.

Common Pitfalls and How to Avoid Them

1. New Username Already Taken
   Usernames must be unique across GitHub. If your desired name is taken, try a variation.

2. Broken External Links
   While GitHub sets up redirects, links in your personal website, documentation, or readme files may need updating.

3. Cloned Repositories Stop Working
   Local repos using your old username in the remote URL will stop pushing/pulling. Update the remote URLs with the new username.

4. GitHub Pages May Break
   If you use GitHub Pages (username.github.io), it might stop working. Set it up again under your new username.

5. Username Change Not Reflected Immediately
   Some systems or integrations may take a few minutes to reflect the change. Clear cache or log out and log back in if needed.
