WordPress can presently export all of its content via WXR, and then import that 
through the WordPress Importer plugin. That process includes all posts, terms, 
menus, comments, and users, but it doesn’t touch options. In addition to 
general settings, options can include widget configurations, plugin settings, 
theme settings, and lots more. This can be very time-consuming to migrate 
manually. WP Options Importer aims to fill that void and save us all a lot of 
time.
WP Options Importer allows you to export all options to a JSON file, and then 
you can selectively import them into another WordPress installation. The import 
process is very transparent, and it even shows you what data you’ll be 
importing. Lastly, it gives you the option to override existing settings or to 
skip options that already exist.
