Oracle DB to PostgreSQL Modernization

Hexaware’s Oracle to PostgreSQL Migration offering provides enterprises with a comprehensive, automated solution to modernize legacy Oracle databases using the Amaze® accelerator platform. This intelligent, AI-driven solution simplifies the complex migration process, enabling organizations to reduce costs, minimize risk, and accelerate their journey to a scalable, cloud-native open-source database environment.

Key Features:

• Comprehensive Assessment & Discovery: The engagement begins with an automated, in-depth assessment of your Oracle database landscape, including schemas, stored procedures, packages, triggers, views, and SQL scripts. This phase uncovers technical debt, integration dependencies, and migration complexity, generating a detailed readiness report that informs prioritization and planning.

• Pilot for 3 Databases: A pilot migration of three representative Oracle databases validates the automated conversion approach. Amaze® facilitates up to 70% automation in schema and database object conversion, complemented by manual refactoring of Oracle-specific PL/SQL, enhancing compatibility with PostgreSQL. The Pilot ensures business continuity by validating data integrity, application performance, and security in the new environment.

• Automated Schema & Code Conversion: Amaze® converts tables, indexes, functions, stored procedures, and triggers to PostgreSQL-compliant equivalents while refactoring application inline queries and connection pooling. Automation accelerates conversion timelines and reduces errors, enabling faster migration and go-live readiness.

• Data Migration & Validation: Data is migrated efficiently to PostgreSQL using AWS Database Migration Service (DMS), ensuring near-zero data loss and high throughput. Automated data correction and reconciliation scripts address migration discrepancies. Hash-based, row-level validation assures output parity and compliance.

• Cloud-Native PostgreSQL Architecture: The solution designs scalable, high-availability PostgreSQL environments optimized for cloud deployment on AWS Aurora or other managed PostgreSQL services. This architecture supports hybrid and multi-cloud strategies with enhanced disaster recovery and replication capabilities.

Business Benefits:

• Significant Cost Reduction: Achieve 50-70% savings by eliminating expensive Oracle licensing fees and reducing database administration overhead. Operational costs decline with streamlined infrastructure and management on open-source platforms.

• Accelerated Migration Timelines: Experience 30-40% faster migration enabled by Amaze®’s AI-driven automation capabilities and structured migration execution frameworks, reducing overall project timelines and accelerating time to value.

• Improved Performance & Scalability: PostgreSQL delivers enterprise-grade reliability with advanced indexing, JSON support, and parallel query execution, resulting in improved performance on large-scale data workloads.

• Reduced Vendor Lock-in: Transition to a flexible, open-source database environment that enables greater cloud portability, vendor independence, and ease of integration with modern applications and analytics platforms.

• Future-Ready Architecture: Build a scalable, cloud-optimized PostgreSQL foundation ready for emerging technologies such as AI/ML, big data analytics, and hybrid cloud deployments, empowering innovation and digital transformation.
