Database Migration

MySQL to PostgreSQL Migration

PostgreSQL offers better JSON support, more advanced indexing, and superior extensibility. We handle the full migration — schema conversion, data transfer, stored procedure rewriting, and application-layer query updates.

Need this done for your project?

We implement, you ship. Async, documented, done in days.

Start a Brief

Schema Conversion

MySQL data types map to PostgreSQL equivalents: TINYINT becomes SMALLINT, ENUM becomes custom types, AUTO_INCREMENT becomes SERIAL or IDENTITY. We handle charset differences, collation mappings, and index type translations.

Data Migration

Large tables migrate using parallel COPY operations with integrity checksums. We handle binary data, unicode edge cases, and MySQL's quirky NULL handling. Foreign keys are deferred during bulk load for maximum throughput.

Application Updates

We update your application's SQL queries for PostgreSQL syntax differences: GROUP BY strictness, string concatenation, date functions, and LIMIT/OFFSET behavior. ORM configurations get adjusted for PostgreSQL-specific features.
