PLX Multi-Environments manages separate Development, Staging, and Production environments directly from within the WordPress Admin screen.

Once the separate configuration files have been installed and your existing wp-config.php settings have been backed up
you\’re then free to enter each of your environments database settings. When you push your files between servers you no
longer need to edit the configuration.

Important: Although the plugin will automatically backup your current settings to wp-config.backup.php, we strongly recommend backing up
your wp-config.php file before completing the plugin installation.
