Utilising SEND to Production button

How do i apply my configurations to production by send button, how does the send button identify my production environment where to set the production server details.

This is done automatically if you are using the SaaS version. If not you need to have demo and a prod instance and tell the demo where to send in the config. The demo needs to have permission on the prod to apply the newly promoted config

Yeahh, but where do I configure my Prod (Higher environment) details.

In the demo you would add
PRIMERO_PROMOTE_CONFIG_PROD_HOST: "primero.mydomain.com" to the ansible inventory file and redeploy
