Strategic Legacy Modernization
COBOL to containers. Mainframes to microservices. We preserve institutional knowledge while eliminating technical debt.
Twenty-year-old ERP systems built on Fortran. AS/400 databases that power manufacturing lines. VB6 applications running critical financial processes. These systems work—until they don't. Our modernization approach extracts embedded business logic, rearchitects data models, and transitions to cloud-native architectures without disrupting operations. We've executed complex migrations—like moving 4.2 million lines of COBOL to Java and transforming IMS databases to PostgreSQL—while maintaining operational SLAs above 99.9%.
Technical Approach
01
Discovery & Risk Mapping
We begin with a forensic analysis of your legacy environment, mapping dependencies and uncovering critical business rules hidden within millions of lines of code. This process identifies the 20% of code delivering 80% of the value, forming the foundation of a zero-risk migration strategy.
- BINARY DECOMPILATION ANALYSIS
- COMPLEXITY METRICS & HEAT MAPPING
- DATA MODEL REVERSE ENGINEERING
- DEPENDENCY GRAPH VISUALIZATION
02
Incremental Transition
We ensure business continuity by running legacy and modern systems in parallel. Using bi-directional data synchronization and gradual traffic migration, we transition workloads with zero operational disruption, guaranteeing rollback capability at every stage.
- PARALLEL SYSTEM OPERATION
- BI-DIRECTIONAL DATA SYNC
- GRADUAL TRAFFIC MIGRATION
- AUTOMATED ROLLBACK PROCEDURES
03
Bridge Architecture
Instead of a risky 'big bang' rewrite, we build a bridge. We expose core legacy functions through modern APIs, allowing you to build new interfaces and functionality incrementally. This hybrid approach de-risks the project, preserves decades of institutional knowledge, and delivers measurable ROI in months.
- API FAÇADE PATTERNS
- MICROSERVICES DECOMPOSITION
- LEGACY CONTAINERIZATION
- GRADUAL UI REPLACEMENT
The Modernization Dividend
Modernizing isn't a cost; it's an investment that unlocks exponential gains in performance, security, and scalability.
Measurable • Validated • Operational
Radical Performance
Go from hours-long batch jobs to real-time processing. We unlock parallel processing capabilities that turn nightly reports into live dashboards, giving you instant visibility into your operations.
Eliminate Inherited Risk
Retire systems with unpatchable vulnerabilities. We harden your infrastructure with modern authentication and protocols, reducing security incidents by over 90% and ensuring compliance.
Peak Load Handling
Move from rigid capacity planning to elastic, on-demand scaling. Our cloud-native architectures automatically handle massive traffic spikes—like a 4,000% surge on Black Friday—with zero degradation.
Technical Challenges Addressed
What Most Teams Miss
PUNCH-CARD ERA PROTOCOLS
Fixed-length records from 1987 specifications. Fixed-point arithmetic with implied decimal positions. We decode data structures that haven't been documented since the original developers retired in 2003.
EMBEDDED BUSINESS RULES
Critical logic lives in COBOL COPYBOOKs written by consultants in 1995. Inventory allocation algorithm depends on undocumented bit flags. We extract and codify institutional knowledge before it disappears.
MINUTE-BASED TIME SLICES
Manufacturing schedules run on 15-minute boundaries. Financial batches process at midnight UTC regardless of timezone. Modern event-driven architectures must maintain temporal compatibility during migration.
32-BIT DATE FIELDS
Year 2038 problem looms in embedded systems. Mainframe date formats predate Unix epoch. Migration must handle date arithmetic that spans 50 years of business logic without breaking historical reporting.
DORMANT CODE PATHS
Dead code scanning shows 67% of COBOL modules haven't executed in 3 years. But that one 1998 tax calculation subroutine? Runs once quarterly and handles $40M in compliance. Risk assessment requires runtime analysis, not static metrics.
EXPERTISE ATTRITION
Original IMS database administrator retired in 2018. Last remaining COBOL expert plans exit in 6 months. Knowledge transfer happens through code archaeology and documentation reverse engineering—not handoffs.
Modernization Technology Stack
We work with both legacy and modern technologies to ensure seamless transformation and future compatibility.
Mainframe Migration Without the Downtime
Green-screen terminals. IMS databases. COBOL programs written when smartphones didn't exist. These systems run your business, but they're creating risk you can't afford. Our modernization approach maintains operations while incrementally replacing every component—from byte-order dependencies to user interfaces optimized for 3270 terminals.
