To migrate the Airbyte internal Postgres database to an external RDS instance, follow these steps: 1. Create a backup of the internal Postgres database using

pg_dump

or a similar tool. 2. Import the backup into your RDS instance. 3. Update the Airbyte configuration to use the RDS instance by modifying the

.env

file. Set the following environment variables:

DATABASE_USER=postgres DATABASE_PASSWORD=password DATABASE_HOST=host.docker.internal DATABASE_PORT=3000 DATABASE_DB=postgres

Replace the values with the appropriate credentials for your RDS instance. If you need to separate the Config Database and the Job Database, you can specify separate parameters for each ([source](https://docs.airbyte.com/operator-guides/configuring-airbyte-db)). 4. If you're using Kubernetes, update the Helm values to disable the internal Postgres and configure the external database:

yaml postgresql:   enabled: false externalDatabase:   host: ${db_host}   user: ${db_user}   password: ${db_password}   database: ${db_name}   port: ${db_port}

Replace the

${...}

placeholders with the appropriate values for your RDS instance ([source](https://discuss.airbyte.io/t/2914)). 5. Redefine the

DATABASE_URL

and

CONFIG_DATABASE_URL

environment variables to include the correct host, port, and database, as well as any extra parameters required by the JDBC driver ([source](https://docs.airbyte.com/operator-guides/configuring-airbyte-db)):

DATABASE_URL=jdbc:<postgresql://host.docker.internal:3000/postgres?ssl=true&sslmode=require> CONFIG_DATABASE_URL=jdbc:postgresql://<host>:<port>/<database>?<extra-parameters>

6. Restart Airbyte to apply the changes. Please note that you might need to grant your RDS instance public access to allow communication between your local Postgres database and the remote RDS instance ([source](https://airbyte.com/tutorials/postgres-to-redshift-data-replication)). For more information on configuring Airbyte with an external Postgres database, refer to the [official documentation](https://docs.airbyte.com/operator-guides/configuring-airbyte-db).
