programatically Import Magento 1 orders into Magento 2 site

I have exported Magento-1 Order details into csv file.

I Need to import those order details into Magento2 site via programatically.
I can able to update the order grand total already present in the orders.

Need to create a order programatically,

Here i have mentioned the Order update code

<?php
use MagentoFrameworkAppBootstrap;
include('app/bootstrap.php');
ini_set('display_errors', 1);
$bootstrap = Bootstrap::create(BP, $_SERVER);
$objectManager = $bootstrap->getObjectManager();
use MagentoSalesModelOrder;
$orderId = 000000002;
$objectManager = MagentoFrameworkAppObjectManager::getInstance();
$order = $objectManager->create('MagentoSalesModelOrder')->load($orderId);
$orderState = Order::STATE_PROCESSING;
$order->setGrandTotal(50.00);
$order->setState($orderState)->setStatus(Order::STATE_PROCESSING);
$order->save();
echo "Order Updated successfully";

Can anyone suggest some ideas for create order via similar method.

Thanks in Advance.
