Key Highlights

  • OptiSol partnered with a leading FinTech firm to migrate their database infrastructure from Oracle to PostgreSQL, aiming to modernize their systems and reduce operational overheads.
  • The client struggled with high Oracle licensing costs, vendor lock-in issues, and required a seamless migration with zero downtime to maintain continuous support for their real-time financial operations and critical workflows.
  • OptiSol used the O2PIM framework to automate key tasks like schema conversion, PL/SQL logic transformation, and staged data migration using CDC, enabling a controlled and disruption-free transition to PostgreSQL.
  • The migration helped the client realize major cost savings, boost system performance, and adopt a flexible, fully open-source database platform that could easily integrate with future technologies and evolving business needs.

Problem Statement

01

Rising Licensing Costs: The client was burdened with increasing Oracle licensing and support fees. These recurring costs placed pressure on their IT budget and limited their ability to invest in infrastructure upgrades or innovation.

02

Vendor Dependency: Their reliance on Oracle’s proprietary ecosystem made it difficult to adopt new-age technologies. This dependency restricts flexibility in integrating modern tools and adapting to evolving FinTech industry requirements.

03

Migration Complexity: Migrating to PostgreSQL was technically complex. Differences in data types, stored procedures, and database structures required specialized handling to ensure consistent performance and avoid data loss or functionality gaps.

04

Zero Downtime Need: As a real-time financial services provider, any system downtime could affect customer trust. The client needed a migration approach that guaranteed uninterrupted services and business continuity throughout the transition.

Solution Overview

01

OptiSol leveraged its iBEAM O2PIM framework to perform a structured Oracle to PostgreSQL migration, starting with a detailed assessment of existing workloads, object dependencies, and application touchpoints to minimize potential risks and disruptions.

02

The framework’s schema conversion module automatically transformed database structures like tables, indexes, views, and constraints. This ensured PostgreSQL compatibility and reduced manual intervention, while maintaining consistency across legacy and target environments.

03

A built-in PL/SQL converter in O2PIM refactored stored procedures, functions, and triggers into PL/pgSQL equivalents. This helped preserve core business logic with minimal manual rework and supported faster development cycles of post-migration.

04

Data migration was carried out in planned stages using parallel processing and Change Data Capture (CDC) techniques. This ensured real-time synchronization between the Oracle and PostgreSQL databases, enabling near-zero downtime during cutover.

05

After migration, OptiSol conducted comprehensive data validation, regression testing, and performance tuning to ensure the new PostgreSQL setup met required SLAs and supported high-volume, real-time financial transactions efficiently.

About The Project

This success story captures how OptiSol partnered with a prominent FinTech company to modernize their data infrastructure by migrating from Oracle to PostgreSQL using the O2PIM framework. The client’s existing Oracle setup was becoming increasingly cost-prohibitive and lacked the flexibility required for innovation and integration. Given the criticality of their systems, the client needed a zero-downtime, risk-mitigated transition to an open-source database platform.

Through a structured and semi-automated migration process enabled by O2PIM, OptiSol delivered a scalable, future-ready PostgreSQL environment. The transition not only helped cut licensing costs but also paved the way for more agile and efficient data operations.

FAQs:

Why should a FinTech company migrate from Oracle to PostgreSQL?

Migrating to PostgreSQL helps reduce high licensing costs, remove vendor lock-in, and adopt a flexible, open-source stack that integrates better with modern tools and scales with evolving FinTech requirements.

What is O2PIM, and how does it simplify the Oracle to PostgreSQL migration?

O2PIM is OptiSol’s proprietary migration framework that automates schema conversion, PL/SQL transformation, and data migration, ensuring minimal manual effort, high accuracy, and near-zero downtime during the Oracle to PostgreSQL transition.

Is PostgreSQL secure and compliant for FinTech-level operations?

Yes, PostgreSQL supports enterprise-grade security features like encryption, role-based access, and audit logging, making it suitable for regulated industries such as FinTech, where data privacy and compliance are essential.

Can PostgreSQL handle real-time financial transactions at the same level as Oracle?

PostgreSQL is capable of high-performance transaction processing, supporting large data volumes and concurrent workloads, especially when tuned and configured properly for low-latency, real-time FinTech operations.

What kind of post-migration support or optimization does OptiSol provide?

OptiSol offers post-migration validation, performance tuning, query optimization, and ongoing database monitoring to ensure the PostgreSQL setup remains stable, scalable, and aligned with business and technical objectives.
