Legacy System Integration
Your legacy system works. It handles core business processes reliably and contains years of irreplaceable data. But it does not talk to modern tools, and your team wastes hours bridging the gap manually. Anubiz Labs integrates legacy systems with modern platforms — extracting data, connecting workflows, and extending capabilities — without the risk and cost of a full rewrite.

API Wrappers for Legacy Systems
Legacy systems were built before APIs were standard practice. They store data in proprietary databases, use custom protocols, and expose functionality through thick client interfaces that no modern application can communicate with. We build API wrappers that expose your legacy system's data and operations through modern REST or GraphQL endpoints.
These wrappers translate between the legacy system's internal data model and a clean, modern API interface. Modern applications interact with well-documented endpoints and receive standard JSON responses — they never need to know that the underlying system runs on COBOL, FoxPro, or a 20-year-old Oracle database.
We handle the complexity of legacy data formats, character encodings, stored procedures, and proprietary business logic inside the wrapper layer, presenting a simple and consistent API to all consumers.
Database-Level Integration
When a legacy system has no API and no extensibility mechanism, direct database integration is often the most practical path. We build read and write connectors that interact with legacy databases — SQL Server, Oracle, DB2, MySQL, PostgreSQL, Access, or flat file datastores — while respecting the application's data integrity rules and business logic.
Database-level integration requires careful analysis of triggers, stored procedures, constraints, and implicit business rules that the application enforces. We reverse-engineer these rules to ensure our integration never puts the database in an invalid state that would confuse or break the legacy application.
Incremental Modernization Strategy
Replacing a legacy system all at once is expensive, risky, and often unnecessary. We recommend an incremental approach — wrap the legacy system with modern interfaces, build new features on modern platforms, and gradually migrate functionality as business needs justify the investment. The legacy system remains operational throughout, and each modernization step delivers immediate value.
This strangler fig pattern lets you modernize at your own pace without a big-bang migration. New customer-facing features run on modern technology while the legacy system continues handling back-office operations it was built for. Over time, the legacy system's responsibilities shrink until it can be retired naturally.
Each integration point we build is designed to work whether the legacy system stays or goes. If you eventually replace it, the modern APIs remain unchanged — only the underlying connector needs updating.
Data Synchronization and Reporting
Legacy systems often hold the most complete and accurate business data in your organization, but extracting it for reporting is painful. We build synchronization pipelines that replicate legacy data into modern analytics platforms, data warehouses, or reporting databases — giving your team access to historical data through modern tools without modifying the legacy system.
Synchronization runs on configurable schedules with change detection to minimize load on legacy databases. Data transformations clean and normalize legacy formats into structures that modern BI tools handle natively. Your leadership gets dashboards and reports that combine legacy data with data from modern systems in a unified view.
