Really just FYI…
If you clone a multisite instance the primary domain doesn’t get replaced throughout the database, namely not in the wp_site and wp_blogs table.
Nor does ‘DOMAIN_CURRENT_SITE’ get updated in wp-config
FWIW, I find cloning easier/better to use than cloning because it’s easier to update an active site that functions as a blueprint than to delete and redefine blueprint regularly, but less so with multisite.
