# Migrate MySQL to PostgreSQL: Data Types & SQL Rewrites

**[DBconvert](https://daily.dev/sources/dbconvert)** · 18 min read · 0 upvotes · 0 comments

## Summary

A practical walkthrough for migrating from MySQL to PostgreSQL, covering the full process: schema assessment, data type mapping (AUTO_INCREMENT, ENUM, unsigned integers, zero dates), SQL dialect rewrites (backticks, LIMIT syntax, IFNULL, GROUP_CONCAT, ON DUPLICATE KEY), stored procedure porting to PL/pgSQL, validation strategies, and low-downtime cutover using CDC. Includes copy-paste before/after SQL examples for common MySQL-isms and a comparison of migration tools (DBConvert, pgloader, AWS DMS).
