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.
Run a single site to multisite import. No PHP deprecated warnings should output to the console. No PHP warnings when moving plugins and themes file assets.
