If you ever attempted to move and restore a WordPress website you know that it's a difficult task to take care of. People experienced: database issues, lost data, formatting and settings, missing graphics and of course other horrible situations.
It definitely sounds like a lot of hard work with possibly terrible outcomes.
Just imagine yourself being an authority blogger, small business owner or consultant and having to go through long tasks of setup, configuration, customization, etc. to get everything running properly. You can literally spend long hours or even days trying to figure out what exactly to do to have your blog or business site moved, restored and later on up and running as before.
