    Hi Matt,

    Welcome to WPMU Dev community!
    I hope you're having a great weekend! :slight_smile:

    You can use our Domain Mapping plugin, found here:

    There are some things you need to configure for this plugin to work.

    1. Install Domain Mapping plugin through WPMU Dev Dashboard. Once installed, log in through FTP.
    2. Go to /wp-content/plugins/domain-mapping/, you will see a sunrise.php file.
    3. Move that file (not copy) to /wp-content/ folder. The file path should now be: /wp-content/sunrise.php
    4. Then, open your wp-config.php file. It's located within the root of your WP installation.
    5. Add the following line above this code: /* That's all, stop editing! Happy blogging. */
    define( 'SUNRISE', 'on' );

    Now, go to your Network Admin > Plugins, and Network Activate the Domain Mapping plugin.

    Further and more detailed instructions can be found in the usage part of the plugin page:

    Let me know if this helps! :slight_smile:
    Thanks Matt!
