Capability
Mission Systems Modernization
Modernize critical systems without mission downtime. Reduce sustainment risk and increase interoperability.
What you get
Measurable outcomes from delivery.
Legacy mission systems can’t be replaced overnight — they’re running operations that don’t pause for migrations. The strangler fig pattern incrementally replaces legacy functionality by routing new capabilities through a modern layer while the old system continues operating. Over time, traffic shifts entirely to the new system with zero downtime.
This approach eliminates the “big bang” migration risk that has derailed federal modernization programs for decades. Each increment delivers measurable value and can be independently validated, giving program offices confidence and evidence for continued investment.
-
Zero-downtime modernization
Migrate, refactor, and replace critical systems while they continue operating. Phased approaches that eliminate the ‘big bang’ cutover risk that kills modernization programs.
-
Interoperability
Connect legacy systems to modern platforms through APIs, event streams, and data integration layers. Make old systems useful to new capabilities without rewriting everything.
-
Reduced sustainment cost
Move from expensive, custom maintenance to repeatable, automated operations. Containerize, standardize, and document so your team can sustain what we modernize.
Deliverables
We deliver modernization as working, deployable capability.
- Legacy system assessment and modernization planning
- API and integration layer development
- Data migration and synchronization
- Application refactoring and containerization
- Phased cutover planning and execution
- Interoperability and standards compliance
- Operational documentation and training
- Performance and reliability engineering
Our expertise
Our engineers have migrated systems across defense, health, and civilian agencies — including systems that couldn’t go offline for even a maintenance window.
-
Legacy integration
Build integration layers that let legacy systems participate in modern architectures — APIs, event buses, data replication — without requiring full rewrites of working code.
-
Phased migration
Design migration approaches that move capability incrementally. Strangler fig patterns, parallel running, and canary deployments that eliminate big-bang risk.
-
Platform modernization
Containerize, automate, and standardize legacy applications for modern infrastructure. Reduce operational risk while improving deployment speed and reliability.

FAQ
Common questions about our delivery model.
Can you modernize without downtime?
That’s our standard approach. We use phased migration with parallel running, canary deployments, and rollback capability at every stage. Mission systems stay operational throughout.
What if our legacy system has no API?
We build one. We’ve wrapped systems with REST APIs, built database replication layers, and created event adapters for systems that were never designed for integration.
How do you handle data migration?
Phased, validated, and reversible. We migrate data incrementally with reconciliation checks at every stage. Full parallel running before cutover so discrepancies are caught early.
Do we need to rewrite everything?
Almost never. We modernize incrementally — containerize what works, replace what doesn’t, and build integration layers for everything in between. The goal is reduced risk and cost, not perfection.
