Copy site to production server

We have a problem with a site called Parlacar in which we use WordPress and Avada. The site works well on the development server. When the site is imported to the test server it cannot be navigated and gives HTTP/1.1 301 Moved Permanently. When importing the site to the production server several parameters of configuration, styles, fonts and logos lose their original values and the site is not correct. How can we solve it?
