38%DB2 to PostgreSQL migration modernizes your database, enabling future expansion, cloud adoption, and innovation.
Reduce operating costs: No expensive licensing fees and lower infrastructure costs.
Drive flexibility: Freedom from vendor and a vast choice of deployment, cloud, and support options.
Expedite innovation: Quicker feature delivery and easier adoption of AI and analytics.
Improve scalability: Eliminate legacy database constraints.
Simplify maintenance: Replace custom DB2 workarounds with a platform supported by a global community and continuous updates, with less requirements for in-house expertise.
Build in resilience: Replication and backup strategy set up as part of the migration.
Keep integrations intact: Database connections and dependencies updated so existing applications keep working.
Preserve behavioral parity: Stored procedures and business logic converted and validated.
Reinforce security and reliability: Streaming replication, point-in-time recovery, and role-based access control configured as part of the migration.
Stabilize performance with faster, more predictable response times for the applications your business depends on daily.
Let us help you rebuild what’s holding you back.
Modernize your legacy databases with reliable, low-risk DB2 to PostgreSQL migration. Corsac preserves data integrity, optimizes schemas and SQL compatibility, drives performance, and reduces maintenance costs. You gain an advanced system ready to scale and accommodate cloud technology.
We aren’t a full-stack agency. We’ve built our team, processes, and tech strategy specifically to tackle legacy issues and help mid-market players scale and innovate.
We integrate with your workflows, minimizing interference with your developers. While utilizing your Git, CI/CD, and tools, we operate independently, letting your team focus on their work.
Your aging system drains your business resources through slow hiring, security gaps, and delayed launches. We reduce these “dark tech debt” losses before they impact your revenue.
We remove legacy barriers preparing your systems for advanced tech. You can embrace new tools with the future-ready and ROI-driven architecture.
Modernization efforts will be ineffective if the core issue is institutional rigidity. We reveal hidden limits and help grow with flexibility.
We treat your system efficiently: evolve the functioning parts and replace only the ones that require change.
To shape the optimal migration strategy, we assess your DB2 environment, database objects, dependencies, and processes. We evaluate risks and required effort, ultimately creating a detailed plan for a predictable PostgreSQL migration.
Database schemas, tables, indexes, data, and SQL code are migrated from DB2 to PostgreSQL with precision and automated validation. We retain data integrity, transfer database objects, and validate migration accuracy against the source system.
Verify migrated schemas, data, stored procedures, and application functionality to confirm the behavioral parity between the DB2 system and its PostgreSQL equivalent.
Conduct thorough testing to check data integrity, object consistency, business rules, and SQL conversion results.
Maximize performance by optimizing queries, indexes, execution plans, and PostgreSQL configuration.
Test functionality, integrations, and performance, eliminate bottlenecks, and refine the database to enable resilient and scalable operation.
Perform a controlled implementation with continual expert guidance. We monitor the database after launch, delivering ongoing support, performance upgrades, issue fixing, and optimization. You get minimal downtime and operational stability.

We focus on modernization for companies unable to grow due to aging systems
We replace only what must be changed, protecting your investment and CTO’s credibility.
HIPAA, HL7/FHIR, SOC2, GDPR, ISO compliance is integrated into every stage.
Integrating into your Git, CI/CD, and workflow tools, we make modernization visible, testable, and traceable
We uncover hidden costs, feature delays, and security gaps and offer ways of their removal
By providing CEOs stakeholder-ready roadmaps and progress metrics, we enable well-grounded transformation
They fulfill your task without seeking to address the issue at the root
Dispersing the focus, they fail to meet specific Healthcare G and other industry requirements
Generalized practices, regardless of the product, team, or business specifics
Initiate full rewrites instead of using the working parts and considering business context
Insufficient collaboration leads to poor handover, with documentation debt and weak enablement.
Development happens in isolation, prioritizing code delivery over actual business value.
With DB2 to Postgres migration, you can cut licensing costs, break free from vendor dependency, and advance your database platform. A remarkable open-source database, PostgreSQL grants speed, stability, and scalability to meet modern business demands. It allows for implementing cloud technologies and spurs innovative expansion.
Our DB2 to PostgreSQL migration process includes schema validation, automated and manual data checks, functional testing, and performance testing. Before the system goes live, we confirm that all database objects, business rules, and application functionality work correctly and meet the original DB2 behavior.
If you have DB2 UDB PDF documentation, database specifications, or technical design documents, we use them to better understand the existing environment. It helps verify database objects, minimize migration risks, and expedite planning. This documentation complements the automated database analysis we conduct to collect the necessary knowledge about your system.
When we migrate DB2 to PostgreSQL, our team necessarily adapts applications to the new PostgreSQL environment. We update database connections, SQL queries, drivers, and database dependencies. Based on the technical need, we also refactor database structures for greater compatibility, maintainability, and reliable performance in the long term.
Our approach is focused on minimal business disruption. We meticulously plan migration and cutover, perform thorough testing before implementation, and provide a gradual, controlled production deployment. Then, we monitor and optimize performance, delivering continual support to ensure stable PostgreSQL operations.
