Migrate to a new domain - Upfront

We developed the site on debutdancestudio.com/dev with the Spirit theme. We moved the files from the /dev/ directory to the httpdocs or root. Site is working fine but looks like the version of WPMU DEV Dashboard is not connected. Since in this support chooser, I do not see the Spirit theme as an option. Also, when linking the logo in the menu bar, we choose homepage and it gives it the URL debutdancestudio.com/dev/ I can manually do a URL but figured should do it the right way.

How do I register the dashboard correctly?
