Hello Bertus Kruger,

Solution for Odoo.sh

If you are using odoo.sh as a hosting server, then you can make staging branch, and restore a production copy database over there.
Please note that you also need to push the custom code(if any) to staging branch.(you can do this in trial project also)

Solution for Custom Server

If you have any custom server, make a new environment with production copy database and custom code, run that to different port and path rather than production.

Thanks & Regards,
