How to Update changes from UAT to PROD

I have created new doctype and in an existing doctype added new field. Both doctypes are related to frappe not in my custom app.

Now i need to push these changes from UAT to Prod.

How can i do this.?

Maybe it will break your production. We suggest everyone: if you want to create a custom doctype, please do so using a custom app. If you want to add a field to an existing doctype, you can do that, but you should also export it to your custom app. Then, publish your custom app on GitHub so that whenever someone installs that app, they can easily install it on any site without any issues. This way, you can easily pull and push the code as needed.
