# Environments

> Overview of the dual-environment setup in UDI Connect (Preview and Production Environments).

## Understanding the Two-System Landscape

UDI Connect now operates within a **dual-environment landscape**, consisting of the following two environments:

* **Preview Environment** – Connected to the **authorities’ test systems**. This environment allows safe testing, validation, and preparation before live submissions.
* **Production Environment** – Linked to the **official productive systems** of the authorities. This is the live environment used for regulatory submissions.

This setup ensures that all onboarding, configuration, and submission activities can be validated in the Preview environment before going live in Production.

***

## Switching Between Environments

In the **Settings** section, you can now choose the desired environment through the **“Go To App”** dropdown menu.

* By default, clicking **Go To App** will redirect you to the **Production** environment.
* To work in the Preview environment, simply select **Preview** from the dropdown menu before navigating.
