### PostgreSQL for Process Mining Airflow databases

For Process Mining on Automation Suite 2023.10.9 or higher, you can now choose to use PostgreSQL for the `AutomationSuite_Airflow` database. If you choose not to use PostgreSQL and keep using Microsoft SQLServer, Process Mining on Automation Suite will run with a legacy version of Airflow.

Refer to [SQL Requirements for Process Mining](https://docs.uipath.com/automation-suite/automation-suite/2023.10/installation-guide/configuring-sql-databases#sql-requirements-for-process-mining) for more information on how to set up a PostgreSQL `AutomationSuite_Airflow` metadatabase.
:::important
You are recommended to move to PostgreSQL for the Airflow database, as PostgreSQL runs with the latest versions of Apache Airflow. Latest versions of Apache Airflow have various functionality, performance, and security fixes that older versions lack.

### Upcoming removal

In Process Mining on Automation Suite 2025.10, we will no longer support Apache Airflow versions older than Airflow 2.9.0. This implies that, starting with Process Mining on Automation Suite 2025.10, you can no longer use Microsoft SQL Server for the `AutomationSuite_Airflow` database. Newer Airflow versions do not support Microsoft SQL Server for Airflow meta databases.

For the `AutomationSuite_Airflow` database, a PostgreSQL database is required for Process Mining on Automation Suite 2025.10. This will apply to both new installations and existing installations that upgrade to 2025.10.

You can already start using PostgreSQL for the `AutomationSuite_Airflow` database in Process Mining on Automation Suite 2023.10.9.
