Remove site and 301 to new domain

Hey,

I have WP multisite set up with 20+ sites

I would like to move one of those sites its own domain.

I can delete the site from the multisite domain easily enough BUT how do I 301 any traffic to the old URL to the new domain (NB new domain will have different structure so just needs to go to new domain index page.

http://www.multisite.com/moveme/ >>> http://www.moveme.com/

Hope this makes sense 🙂

Thanks.
David
