Migrating into multisite network

I’m migrating sites that are currently stand alone into a multisite network to help make things a bit easier for me to manage.

It looks like the on page/post data (meta titles, descriptions etc) came over with the WP core export/import.

I’m curious if there’s a way to export/import the plugin settings as well?

For example I’ve made some settings modifications in the schema and webmaster settings that didn’t seem to migrate with the WP core export/import.
