Transfer edits to the new version

Good evening, everyone.
There is an IM store on the php engine - shop with open source.
the address where all edits to the new version of the http://test.kts-samara.ru/in_m8/

heres the old version of the site. https://www.kts-samara.ru/in_m8/akkumulyatory-batarei..
previously made edits should be moved.
There is a red price on the site. It is taken from the product card: the admin panel > price2 is substituted on the site. Further - if the user has a status (admin panel > statuses) "Regular customer" then he buys at the red price. OR if an ordinary customer without the status "Regular" puts 2 pieces of one product name in the basket, the price of these goods is also changed to the red price. Next, you need to make the layout that is in the photo with the red price.

The price is negotiable.
