The executive producer previously hinted that the performances would be scheduled for a spring 2010 road show.
Murphy has now revealed that cast members will partake in an American Idol-style US jaunt next summer, the New York Post reports.
He said: "We're going to do what American Idol has done and put the kids on the road. It all equals revenue streams for Fox."
The 43-year-old also explained that the programme's song recordings, such as Journey's 'Don't Stop Believin', have been downloaded 400,000 times on iTunes and also equate additional profits for the musical comedy.
He added: "This is a new sort of model. It used to be with TV that you would have the show, then foreign sales, then DVD sales and then syndication sales, but DVD sales have really taken a cut out of syndication.
"This is a whole new way for Fox to earn revenue on a show."
Murphy recently responded to NBC for its decision to exclude the stars of the series from partaking in the annual Macy's Thanksgiving Day Parade.
