I am working on redesigning a website that is currently a PHP website. The new site will be all HTML. I am trying to keep all of the slugs the same. Should I set up redirects?
Currently, the website pages have the .PHP extension in the browser.
Example: https://www.dehartsystems.com/residential.php
The new page will be HTML and the URL will have no file extension.
Example: https://www.dehartsystems.com/residential
Do I need to set up redirects as the file extension will be changing?
