When it is time for the server to go into production, the “real” certificate is installed as clients are getting redirected to the new server.

If you will not be purchasing a trusted key and this will be it, you can download the key from your web browser and install it into your “Trusted Root Authority” key store for your browser. Once that is done, you will bypass all those annoying “website is not trusted” warning. Of course, this isn’t exactly ideal for systems that you’ll be directing your customer to.
