Bruno,
After completion of your configuration in your test tenant with first implementation. You can request for productive system coping your solution profile.
SAP will give you productive system with all configuration and scoping you did in business configuration work-center and rest of other thing you have to perform such as Org Structure, Business role, territory setup, employee etc.
New production system will have new tenant URL and all together new environment.
hope you are looking for the same.
Regards,
