I started a project in Wordpress months ago, I have completely configured the website, design, content, templates etc ... Now I want to create a network of sites, I have configured it and launched it with this manual https://codex.wordpress.org/Create_A_Network, but when I create a new site, the whole site is not duplicated, it's as if I installed Wordpress again, in the new created site.
It is possible that I can create a new site by cloning all the data from the main website?
