The products, attribute sets, prices, categories, etc has been already migrated from Magento 1.x to Magento 2.x. I want to migrate the orders now.

Is it possible to migrate only orders from the magento 2 data migration tool or is there any other way to migrate the orders?

I am also thinking of mapping sales_flat table of magento 1.x to sales_order table of magento 2 and push the csv from mysql.

Is there any other way ?
