What is the best way to copy a site for another region?

Question

Search Engine Optimization

Let's say there is a site-catalog of goods site74.ru, which, as the name implies, works in Chelyabinsk. Then the site96.ru domain was purchased to work also in Yekaterinburg, and the customer decided to simply copy the site to this domain from the first domain. What is the best way to make a copy of the site so that the search engines index it normally? Will it be enough to change the layout and texts on the pages, except for the product descriptions, or will the page descriptions also have to be changed?
