How to Move Posts and Pages From One WordPress Site to Another
Installing the WordPress Installer
Now that we want to import from one WordPress site to another, we must download and install the WordPress installer software first. The plugin is always available for downloads and active installation in the WordPress official plugin directory.
A more ideal way to achieve this is to go to the page from which content is being imported from and click on the WordPress link. a Pop-up box will then appear purposely to let you install the software straight from your site.
