 ## Known Issues
 
-* WordPress Multisites that are using the WordPress (Composer Managed) upstream are currently unable to use Multisite Search and Replace. For those sites, we recommend setting the `search_replace` value to `false` and using WP-CLI via Terminus to perform the Search and Replace. See [Run WP-CLI `search-replace` Manually](/guides/multisite/workflows/#run-wp-cli-search-replace-manually) for more information.
+* WordPress Multisites that are using Integrated Composer, such as the WordPress (Composer Managed) upstream, are currently unable to use Multisite Search and Replace. For those sites, we recommend setting the `search_replace` value to `false` and using WP-CLI via Terminus to perform the Search and Replace. See [Run WP-CLI `search-replace` Manually](/guides/multisite/workflows/#run-wp-cli-search-replace-manually) for more information.
 
 * When using the default Subdirectory search and replace, creating a new multidev with database and files pulled from the live environment will only search and replace the platform domain, i.e. `live-{site}.pantheonsite.io`. To search and replace the correct domain on your live site, immediately follow multidev creation with a database clone either through the dashboard or with Terminus, and select the correct domain as the "from" URL. We are working on handling this seamlessly in the future.
