If you don’t have any external links on your site or just started, you are done!
You can also do this manually by accessing your . htaccess (usually by FTP) and changing the code for every link to an external source to: Redirect 301 /your-former-post-url. html /your-new-post-url. html.
After you’ve utilized the plugin, you can submit your sitemap to Google so they have your updated website information.
