Duplicate opencart store

Dear programmers, This is project is very easy; i will register a new domain and i just need you to copy my old store to the new domain, as long as installing this regular theme on the new store: [login to view URL] (Template files will be provided) The copy must include everything from the previous store (except the theme): products, categories, information,payments methods, etc. and must be working properly. The version of opencart for the new theme may be different and you may need to make some ajustments/upgrades. I also need a module that updates all the products and reflects them on the new store, so i dont have to insert a product 2 times in both stores. This is easy for someone that understands about opencart. Thank you.
