Hello, @joeroot,
Well, migration styling and functionality are not covered in the theme support policy, you should have to use any third-party plugin for the migration of your site, you can try with the duplicator WordPress plugin as well, OR you can contact your hosting provider on this concern.
And relation to the license when migrating the site, please follow the instructions written in this thread: https://www.portotheme.com/forums/topic/site-migration-from-dev-to-live/#post-5083
Best Regards,
PThemes Team.
