Legacy System Modernization

Transform legacy applications into modern, cloud-native systems. Reduce maintenance costs, improve security, and unlock innovation - without business disruption.

Is Your Legacy System Holding You Back?

Warning signs that it's time to modernize

High Maintenance Costs

Spending $100K+/year maintaining old code. Hard to find developers who know COBOL, VB6, or legacy Java.

Security Vulnerabilities

Old frameworks with unpatched security holes. Failed compliance audits (PCI, HIPAA, SOC 2). No modern encryption.

Cannot Scale

System crashes under load. Cannot handle mobile traffic or API integrations. Monolithic architecture impossible to scale.

Slow Development

New features take months instead of weeks. Every change breaks something else. No automated testing or CI/CD.

Data Silos

Data locked in old databases. Cannot integrate with modern tools (Salesforce, analytics, APIs). Manual data exports.

Technical Debt

Code written 10-20+ years ago with no documentation. Original developers long gone. Band-aid fixes everywhere.

Modernization Strategies

We choose the right approach based on your business needs, budget, and risk tolerance

1. Replatform (Lift & Shift)

Move existing application to modern infrastructure (AWS, Azure, GCP) with minimal code changes. Quick migration with lowest risk.

Timeline: 2-4 months
Cost: $$$
Best for: Quick cloud benefits

2. Refactor (Optimize)

Rewrite portions of the codebase to use modern frameworks and cloud services while keeping core logic. Balance of speed and improvement.

Timeline: 4-8 months
Cost: $$$$$
Best for: Improving performance

3. Rebuild (Greenfield)

Build new application from scratch using modern tech stack, replicating business logic. Maximum benefits but higher risk and cost.

Timeline: 8-18 months
Cost: $$$$$$
Best for: Complete transformation

Our Recommendation: Hybrid Approach

Start with Replatform for quick cloud benefits and cost savings. Then Refactor critical modules incrementally (Strangler Fig pattern). This minimizes risk while delivering continuous value. Final Rebuild only if absolutely necessary.

Modernization Process

Zero-downtime migration with continuous business operations

01

Discovery & Assessment

2-4 weeks

Audit existing system architecture, codebase, dependencies, and data models. Document business logic, integration points, and user workflows. Evaluate modernization approaches (replatform, refactor, rebuild) and create ROI analysis.

02

Strategy & Roadmap

2-3 weeks

Choose modernization strategy (hybrid recommended). Design new architecture (microservices, cloud-native, APIs). Create phased migration plan with milestones. Define success metrics and rollback procedures.

03

Pilot Migration

4-8 weeks

Select low-risk module for pilot migration. Build proof-of-concept in new technology stack. Test data migration, integration points, and performance. Validate approach before full-scale migration.

04

Incremental Migration

3-12 months

Migrate system module-by-module (Strangler Fig pattern). Run old and new systems in parallel. Gradual traffic cutover with A/B testing. Continuous validation and rollback capability.

05

Testing & Validation

2-4 weeks

Comprehensive testing: functional, performance, security, integration. User acceptance testing (UAT) with stakeholders. Load testing to ensure new system can handle production traffic. Data integrity validation.

06

Cutover & Support

1-2 months

Final production cutover during low-traffic window. 24/7 monitoring for first 30 days. Hypercare support for critical issues. Post-migration optimization and legacy system decommissioning.

Frequently Asked Questions

How much does legacy modernization cost?
Replatform (lift & shift): $75K-200K for cloud migration with minimal code changes. Refactor: $200K-500K for rewriting critical modules with modern frameworks. Rebuild: $500K-2M+ for complete application rewrite. ROI typically achieved in 12-24 months through reduced maintenance costs (70% savings), faster development (10x), and cloud infrastructure savings (60%).
How long does modernization take?
Replatform: 2-4 months for cloud migration. Refactor: 4-8 months for incremental modernization of key modules. Rebuild: 8-18 months for complete rewrite. We use phased approach: pilot migration (1-2 months) → incremental rollout (3-12 months) → production cutover (1 month). Business continues operating throughout - zero downtime.
What happens to our data during migration?
Data safety is priority #1: 1) Complete backup before migration, 2) Incremental data sync (old to new), 3) Parallel run (both systems active), 4) Data validation (compare old vs new), 5) Gradual cutover (low-risk modules first), 6) Rollback capability at each phase. We have migrated 50TB+ of data with 100% accuracy. Typical data downtime: 0-4 hours during final cutover.
Will modernization disrupt our business?
No! We use Strangler Fig pattern: build new system alongside old, gradually migrate traffic, keep old system as fallback. Users continue working normally throughout migration. Cutover happens in phases (by module/feature), not all at once. Final cutover scheduled during low-traffic window with rollback plan. Risk mitigation: pilot migrations, parallel runs, comprehensive testing, 24/7 support during cutover.
Can you migrate COBOL/mainframe applications?
Yes! We have migrated 30+ COBOL/mainframe systems to modern cloud platforms. Process: 1) Reverse engineer COBOL business logic, 2) Document data structures (VSAM, DB2), 3) Rewrite logic in Java/Python/Node.js, 4) Migrate data to PostgreSQL/MongoDB, 5) Rebuild interfaces as REST APIs/web UIs. COBOL modernization reduces costs by 70%+ and enables modern integrations impossible with mainframes.
What ongoing support do you provide?
Included: 3-month hypercare support post-cutover (24/7 critical issue response, bug fixes, performance tuning, user training). Optional: Monthly retainer ($5K-25K) for: New features, integrations, scaling optimization, security updates, infrastructure management, disaster recovery. Also offer: Legacy system decommissioning, documentation, knowledge transfer to your IT team.
