SQL Server to PostgreSQL Migration

Course Description: SQL Server to PostgreSQL Migration (Complete Hands-On Training)

This comprehensive course teaches you how to successfully migrate databases from Microsoft SQL Server to PostgreSQL, covering real-world methods, tools, strategies, and live demonstrations used by modern Database Administrators, Cloud Engineers, and Data Migration Specialists.

Whether you're moving to PostgreSQL for cost savings, open-source flexibility, or cloud modernization, this course provides a full end-to-end roadmap—from assessment to cutover. Through step-by-step labs, architecture guides, CLI commands, and troubleshooting techniques, you’ll learn exactly how to execute smooth, zero-data-loss migrations using industry-proven approaches.

You will explore multiple migration methods including AWS SCT + AWS DMS, pgloader, SQL Server Export Wizard, SQLines, ETL Tools (SSIS, Pentaho, Talend), and GUI-based DBConvert solutions. Each method is broken down with practical examples, pros/cons, and best-fit scenarios so you can confidently select the right approach for your environment.

This hands-on training also includes detailed comparisons of SQL Server vs PostgreSQL features, data type mapping cheat sheets, schema conversion rules, CDC-based replication, validation techniques, performance tuning, and a full production-ready migration plan.

By the end of the course, you'll be able to migrate databases of any size—from small workloads to enterprise-level systems hosted on-premises or in the cloud.
