Cross DJ on a new PC

Hi there,
I recently have purchased some pionner CDJ's and am in the process of updating my software. I already have purchased Cross DJ, but need to upgrade in order to use the CDJ's with it. However i am also planning on getting a new laptop in the coming months, i was just wondering how can i put this new software on my new laptop in the coming months as i dont want to upgrade now and have to repurchase Cross DJ again when i get a new laptop.
Many Thanks
