To migrate your existing jobs and configurations from an Airbyte EC2 instance to a new Airbyte installation on Kubernetes with an external PostgreSQL database, follow these steps: 1. Export the configuration from your existing Airbyte EC2 instance using the Airbyte UI settings page or the API ([source](https://discuss.airbyte.io/t/1768)). 2. Disable your existing Airbyte EC2 instance. 3. Set up the external PostgreSQL database and configure your new Airbyte installation on Kubernetes to use it. Update the necessary environment variables in the

.env

file or

values.yaml

file for Helm deployment ([source](https://docs.airbyte.com/operator-guides/configuring-airbyte-db), [source](https://docs.airbyte.com/deploying-airbyte/on-kubernetes-via-helm)). 4. Import the configuration to your new Airbyte installation on Kubernetes ([source](https://discuss.airbyte.io/t/1768)). 5. Manually backup and restore the data from your existing Airbyte EC2 instance to the new external PostgreSQL database, as Airbyte does not currently have a built-in migration feature ([source](https://discuss.airbyte.io/t/2903)). Please note that the migration process might require some manual intervention and adjustments depending on your specific setup. Make sure to test the new installation thoroughly before fully switching over to it.
