How can forum administrators ensure a smooth transition when updating PHP versions in their forum software?

Forum administrators can ensure a smooth transition when updating PHP versions in their forum software by first checking the compatibility of their current forum software with the new PHP version. They should also update their forum software to the latest version that supports the new PHP version and test it thoroughly before making the switch. Additionally, administrators should backup their forum data before updating PHP versions to avoid any potential data loss. 

// Sample PHP code snippet for checking PHP version compatibility
if (version_compare(PHP_VERSION, '7.2.0', '<')) {
    echo 'Your forum software is not compatible with PHP 7.2.0 or higher. Please update your forum software.';
} else {
    echo 'Your forum software is compatible with PHP 7.2.0 or higher.';
}
