What steps should be taken to ensure a smooth transition of a PHP system to a new website?

To ensure a smooth transition of a PHP system to a new website, it is important to thoroughly test the new website before making it live. This includes testing all functionalities, ensuring data migration is successful, and checking for any compatibility issues. Additionally, it is crucial to communicate with stakeholders and users about the transition process to manage expectations and minimize disruptions. 

// Example code snippet for testing data migration
// Connect to the old database
$old_db = new mysqli('old_host', 'old_username', 'old_password', 'old_database');

// Connect to the new database
$new_db = new mysqli('new_host', 'new_username', 'new_password', 'new_database');

// Retrieve data from the old database
$old_data = $old_db->query('SELECT * FROM old_table');

// Insert data into the new database
while ($row = $old_data->fetch_assoc()) {
    $new_db->query("INSERT INTO new_table (column1, column2) VALUES ('" . $row['column1'] . "', '" . $row['column2'] . "')");
}

// Close database connections
$old_db->close();
$new_db->close();
