Oracle DB to PostgreSQL Modernization

Hexaware’s Oracle to PostgreSQL migration offering empowers enterprises to achieve cloud-native agility, flexibility, and scalability by transforming legacy Oracle database workloads into modern, scalable PostgreSQL platforms. By adopting PostgreSQL, clients benefit from lower total cost of ownership, enhanced performance, and simplified database management, enabling seamless data operations across hybrid and multi-cloud environments. This transition reduces licensing costs by 50-70% while optimizing infrastructure expenses. The cloud-native, open-source architecture adapts rapidly to evolving business demands while improving availability and reducing operational overhead.

Using our US patented AI-powered Amaze® accelerator, the program starts with an automated, in-depth assessment of your Oracle database environment, including schemas, stored procedures, packages, indexes, triggers, and dependencies. This detailed assessment enables a data-driven migration strategy with minimized risks. A key part of the offering is a pilot migration of 3 representative Oracle databases to PostgreSQL, validating schema conversion, data migration accuracy, and application performance. Amaze® automates up to 70% of the schema and code conversion effort, accelerating timelines and delivering secure, production-ready PostgreSQL databases.

Beyond the pilot, Hexaware collaborates with clients to develop a comprehensive migration roadmap that includes phased Oracle decommissioning, cloud-optimized PostgreSQL deployments, and enterprise-wide database modernization using automated CI/CD pipelines and DevOps best practices. This approach ensures operational continuity, enhanced data governance, and regulatory compliance.
