You definitely won't have to re-install the whole production system, though you may have to re-install the async service on that server. The steps I'd take are:
- Uninstall all CRM component from the server you want to attach into the production environment
- Rerun the CRM setup program on that server, selecting the production environment, and the components you want to install
