Install
This is the repository archive. It installs, but the folder name will carry the branch suffix and updates will not flow.
Install straight from GitHub with WP-CLI:
wp plugin install https://github.com/justinsainton/site-consolidator/archive/refs/heads/master.zipNo built-in updater. New versions won't appear under Dashboard → Updates. Install new releases yourself, or let Git Updater track the repository.
Site Consolidator allows you to take content from any number of multi-site instances and move them over to a different instance. It moves comments and posts, maintaining author attribution and properly redirecting image and post links.
