The Download Button now allows you to download an entire site. You can view the Download button at the Structure of the site, provided you have been allowed a permission at the zDE admin level. On the Site of structure you need to select the Check box "All". This will check all the system level directories. Now click on the Download button. The Site Manager zips all the directories into an archive and downloads them to your machine. You can further upload these directories in any other site of your choice, by using the Upload File option. This facilitates you to shift your entire site from one server to another
