How to Migrate from PostgreSQL to Supabase

Since Supabase is built on PostgreSQL, migration is smooth for most setups. Start by exporting your database using pg_dump to capture your schema and data. Then, create a Supabase project via the dashboard or deploy it locally with Docker. This gives you a clean environment to prepare and verify your migration.

Import your schema and data using psql or Supabase’s SQL editor, making sure relationships and types align. If your app uses authentication, move users into Supabase’s built-in auth system. Update your frontend or services to use Supabase’s auto-generated APIs. Finally, test access rules, performance, and roles before going live and ensure you have fast backups and disaster recovery in place as part of your rollout.
