Migration
Postgres
This guide shows how to migrate any Postgres database to Hydra. This migration requires the pg_dump and psql CLI tools, which are installed automatically as part of the complete PostgreSQL installation package.
Retrieve your Postgres database credentials
- Log in to your provider to get the connection details for your Postgres database. You’ll need the hostname, username, password, and port (if not 5432).
Retrieve your Hydra connection string
- If you’re new to Hydra, create a project.
- Select the project in the Hydra Platform and obtain your credential.
Migrate the database
pg_dump
pg_dump
pg_restore
pg_restore
Import the database to your Hydra project. Use psql to import the Postgres database file to your Hydra project.

- If you’re planning to migrate a database larger than 6 GB, we recommend upgrading to at least a Medium compute instance. This will ensure you have the necessary resources to handle the migration efficiently.
- You can increase the size of the disk on paid projects by navigating to the project Settings tab.
- If you’re dealing with a database larger than 150 GB, we strongly advise you to contact our support team for assistance in provisioning the required resources and ensuring a smooth migration process.
