Legacy Modernization & Migration
Summary
- Target: Organizations whose core systems are hard to change but too important to replace overnight
- Timeline: First risk-reducing improvements within weeks, full journeys planned over several months
- Scope: Architecture, code, data and deployment modernization
- Deliverables: Migration roadmap, modernized components, improved tests and observability
- Engagement: Embedded team working closely with your domain experts and engineers
Risk-controlled modernization
What the modernization team can deliver
Architecture assessment and modernization roadmap
Analysis of your current systems, risks and constraints with a phased migration plan and clear milestones
Incremental replacement using Strangler patterns
Gradual extraction of services and components so legacy functionality keeps working while new parts go live
Test harness and safety net creation
Improved test coverage, contract tests and monitoring to detect regressions quickly during migration
Cloud-ready deployment and performance improvements
Containerization, CI/CD, scaling strategies and performance tuning for modern infrastructure
Modernization without big-bang risks
How the collaboration works
Phase 1: Discovery & stabilization
Understand critical flows, set up monitoring and tests, fix acute stability issues to create a safe baseline
Phase 2: Pilot modernization
Modernize one or two bounded contexts end-to-end to validate approach, tooling and collaboration model
Phase 3: Iterative rollout
Systematic migration of remaining components with regular demos, KPIs and tight feedback cycles
Phase 4: Handover & optimization
Knowledge transfer to your in-house team, documentation and targeted optimizations of the new platform
Frequently Asked Questions
Migration strategy and risk management
Do we need a full rewrite?
Usually not. We prefer incremental modernization where we keep working functionality and replace only what creates risk or blocks progress.
How do you avoid outages?
Through feature flags, blue-green or canary deployments, solid test coverage and the ability to roll back quickly if needed.
Can you work with our existing team?
Yes. The modernization team embeds into your organization and collaborates closely with existing engineers and domain experts.
Which technologies do you use?
We choose stacks that fit your context – often modern JVM, .NET, Node or Python backends, React/TypeScript frontends and cloud services such as AWS or GCP.
How visible is progress?
You get a clear roadmap, regular demos, migration metrics and transparent status reports for every phase of the project.
