This WP-CLI plugin makes the process of moving sites from single WordPress sites to a Multisite instance (or vice-versa) much easier. It exports everything into a zip package which can be used to automatically import it within the desired Multisite installation.
updated export all to only export the currently activated theme and if it is a child theme also export the theme-template/parent theme.
This way not every theme installed in a multisite will be zipped.
