MongoDB to PostgreSQL Migration
Outgrowing MongoDB's flexibility? We design a proper relational schema from your document structure, migrate all data, and update your application to use PostgreSQL — with JSONB columns where they still make sense.
Need this done for your project?
We implement, you ship. Async, documented, done in days.
Schema Design
We analyze your MongoDB collections, identify embedded vs. referenced relationships, and design a normalized PostgreSQL schema. Truly flexible data stays as JSONB columns; structured data gets proper tables with foreign keys and indexes.
Migration Pipeline
Custom ETL scripts transform documents into relational rows, handling nested objects, arrays, and ObjectID references. We run the migration incrementally with change streams to keep the PostgreSQL copy up to date until cutover.
Query Translation
MongoDB aggregation pipelines become SQL queries with CTEs and window functions. Mongoose models get replaced with Prisma, TypeORM, or raw SQL depending on your preference. Full-text search moves to PostgreSQL's tsvector.
