How to swap Shopify website with WordPress?

My customer has Shopify web page on area 1.

He would like me to build a WordPress site on a further domain – area 2.

Soon after developing the internet site and customizing it, he wishes me to transfer the WordPress web page (area 2) to the domain 1. He don’t want want the present Shopify shop on his area 1 and want to remove it and have my crafted site (WordPress with woocommerce) load on domain 1.

TLDR – He want to clear away the Shopify keep from the his recent area (area 1) and desires to transfer the website I crafted with woocommerce from domain 2 to area 1.

How can I do that specifically? Any plugins, equipment you recommend? Any support will be appreciated.

Thank you.
