MySQL to PostgreSQL Migration: Complete Production Guide

Migrating from MySQL to PostgreSQL is not only a data copy.

It is a production journey.

In this video, I walk through a complete MySQL to PostgreSQL migration playbook, from assessment and schema conversion to data movement, validation, tuning, cutover, and post-migration operations.

You will learn how to handle:

MySQL vs PostgreSQL architecture differences
Data type mapping
UNSIGNED integer problems
AUTO_INCREMENT to IDENTITY
MySQL SQL syntax changes
Stored procedure conversion
Trigger conversion
GROUP_CONCAT to string_agg
DATE_FORMAT to to_char
JSON to JSONB
Index conversion
pgLoader migration
AWS DMS migration
DDL conversion
ON UPDATE CURRENT_TIMESTAMP
Post-migration validation
PostgreSQL tuning
PgBouncer
EXPLAIN ANALYZE
Autovacuum
Cutover planning
Rollback strategy
Common post-migration errors
Application and ORM changes
PostgreSQL extensions
MySQL-specific gotchas

This is a practical production guide for developers, DBAs, architects, and engineering teams planning a real MySQL to PostgreSQL migration.
