Please note: These are general steps you can take to create a staging sub-domain in cPanel and copy a website over to it. However, please keep in mind that there might be some extra steps we cannot cover in this guide on any changes you may need to make, that might be specific to your website or CMS (WordPress, Magento, Joomla, etc).
From here, you may need to make some changes to your staging/dev site’s configuration files to ensure it functions properly. Because there are so many different websites and website platforms out there, we cannot cover this part of the process. In the case of WordPress websites, you can refer to the MySQL Settings section of this guide, which explains how to update your wp-config.php file to connect to the new database.
