Firebird Database Assessment & Migration Planning

We conduct a comprehensive evaluation of your Firebird environment — whatever version you’re running, from Firebird 1.5/2.5 through 3.0, 4.0, or 5.0 — including technical debt identification, codebase and data analysis, performance and integration audit, and assessment of SQL compatibility. Also, our experts detect security and compliance risks, outlining potential migration challenges and realistic outcomes.

Firebird Schema & Data Migration

Our engineers map data types, objects, relationships, indexes, and constraints, transforming schema where necessary. We ensure data integrity through the transition thanks to automated source-to-target validation of business-critical information. This approach minimizes migration risk and enables controlled cutover.

Firebird to SQL Server Migration

We adjust your core logic to SQL Server’s architecture by migrating generators/sequences to SQL Server’s IDENTITY or SEQUENCE objects and remapping Firebird’s BLOB sub-types and character sets to SQL Server-compatible equivalents. Our engineers enable integration with cloud services and Microsoft technologies while preventing disruption and minimizing downtime.

Firebird to PostgreSQL Migration

Corsac provides PSQL-to-PL/pgSQL conversion, adaptation of database objects, BLOB storage optimization, and refactoring of Firebird-specific mechanisms — generators, array-type columns, and external (UDF) functions — to enable better system performance, flexibility, and compatibility. All the changes are implemented incrementally to minimize system disruption.

Application & Query Modernization

We decouple outdated Firebird components, eliminate database dependencies, address performance issues, and optimize query patterns and data-access logic. This helps separate the application layer from the underlying database, increase system responsiveness, accelerate delivery, and establish a reliable foundation for future changes and growth.

Migration Testing, Validation & Production Cutover

Before going live, our team validates all critical components, connections, data integrity, functional equivalence, and performance stability. A combination of automated and manual testing maximizes process speed and accuracy while keeping focus on critical business workflows. Backed by reliable rollback procedures, we ensure low-risk migration with more predictable outcomes.

What Makes Corsac a Trusted Partner in Firebird Migration Services

Square icon

Modernization is our core specialization

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.

Square icon

Integration vs. Disruption

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.

Square icon

Identification of hidden expenditures

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.

Square icon

AI & Emerging Tech Enablement

We remove legacy barriers preparing your systems for advanced tech. You can embrace new tools with the future-ready and ROI-driven architecture.

Square icon

Fighting Tech Stagnation

Modernization efforts will be ineffective if the core issue is institutional rigidity. We reveal hidden limits and help grow with flexibility.

Square icon

Respect for Existing Architecture and Leadership

We treat your system efficiently: evolve the functioning parts and replace only the ones that require change.

Our Firebird Database Migration Process

Assessment & Migration Strategy

Thanks to a comprehensive legacy audit, we evaluate the real state of the Firebird environment and build a well-structured migration plan. We assess architecture, codebase, data volumes, and integrations, as well as detect hidden dependencies and security gaps.

Schema & Data Migration

Our engineers extract and transform datasets and move them to the target platform, continuously verifying accuracy and integrity. We also stabilize relationships to avoid compatibility issues.

Application Modernization & Testing

Square

Refactor data-access layer by replacing Firebird client libraries (fbclient.dll, Firebird .NET Data Provider, Jaybird JDBC driver, or legacy IBX/FIBPlus components in Delphi applications) and updating connection settings and APIs

Square

Adapt Firebird-dependent code, queries, functions, and syntax for reliable operation in the modernized environment

Square

Enhance data access and remove specific dependencies that limit compatibility

Square

Test core functionality, performance, data flows, and integrations

Square

Validate business logic to ensure behavioral equivalence between the legacy and modernized environment

Fix connectivity and performance defects if necessary and repeat testing until the benchmarks are met

Production Cutover & Post-Migration Support

We ensure controlled and secure production cutover thanks to final data synchronization, continuous performance monitoring and optimization, and a clear rollback plan that protects essential data. Also, Corsac offers post-migration training for your internal team and shares insights to help them confidently manage the updated system.

    Frequently Asked Questions

    Even if your Firebird system is still working, its maintenance can become increasingly costly and challenging. If you want to eliminate tech debt, build more flexible architecture, minimize security risks, ensure smooth performance, and enable long-term growth, you should consider a Firebird to SQL Server migration.

    Corsac experts go far beyond ordinary data extraction and transformation. Each migration step is backed by comprehensive validation. From mapping data types and defining transformation rules to ongoing checks for behavioral equivalence, we perform all the necessary testing to ensure data accuracy and consistency.

    Firebird database migration costs depend on a wide range of factors, including project complexity, business goals, customization, data volume, and timelines. Thanks to an in-depth legacy system audit, we can assess the scope of necessary improvements and provide transparent and realistic budget forecasts.

    Sure. Before starting the execution phase, we build a clear rollback strategy to minimize risk, protect critical data, and ensure operational continuity. Your existing Firebird environment will remain recoverable through continuous system monitoring, careful data synchronization, and defined reconnection steps.

    Yes. Even after delivery, we track system stability, optimize performance, assess data integrity, and fix unexpected issues. We also provide expert guidance and detailed documentation for your internal team, so you can migrate Firebird to SQL Server with more confidence and manage the system independently.
