PostgreSQL Migration & Upgrades
Migrating to PostgreSQL is more than a database switch — it’s a strategic move to reduce costs, improve performance, and gain flexibility with an enterprise-grade open-source platform. But migrations and upgrades can be risky without the right expertise. Businesses often face challenges with downtime, data compatibility, application rewrites, or extension support.

Whether you’re moving from Oracle, MySQL, or SQL Server to PostgreSQL, or upgrading to the latest PostgreSQL version, our consultants deliver zero-downtime strategies, compatibility fixes, and post-migration optimization
