URGENT Data Transfer from Magento 1 to Mgento 2

Hi,

I have an existing Magento 1 website https://www.swaggerinc.co.uk/ that has already been transferred over to Magento 2 around 1 month ago, i am ready to go live with the new magento 2 website website and shut the old one down, however i need the latest data, orders, customers, inventory changes brought across from the Magento 1 website to the new Magento 2 website before i can change the name servers on the new site and make it active.

This needs to be completed within the next 24 hours

Looking for an expert who has experience in transferring this data across from Magento 1 platform to the magento 2 platform.
