Cloning the site and DB ticks every checkbox. Just make sure to actually clone (carry permissions or re-apply permissions). Set the net DB connection at app/settings.php
Also, make sure that the server meets the system requirements and that all fs permissions are correct.

We are moving off a server with root as public_html to one without. There isn't any routing to replace anywhere that we can see. A new install works fine.
