Redirection on a Domain Mapped Multisite

Has anyone use something like this ->
http://wordpress.org/extend/plugins/redirection/other_notes/

or something else better for managing redirects on a domain mapped multisite? I've ported a static site from html to wordpress. It is one site within my multisite and it will be domain mapped (once we're done). But page names have changed from something like contact_us.html to /contact-us/. etc etc.

Any advice on doing redirects?
Thanks!
