Patching Legacy Is More Expensive Than Replacing It

Agencies maintain 10–20 year-old platforms because replacement feels risky. Maintenance costs compound and security degrades.

Escalating Maintenance Costs

Vendor support expires, patches stop, internal teams spend more time keeping systems alive than advancing mission.

Security Mandates Outpacing Architecture

Zero Trust, cATO, and CMMC requirements can't be met by systems designed before they existed.

Integration Impossible at the Seams

Legacy platforms weren't built for API-first connectivity. Data stays trapped.

Knowledge Locked in Obsolete Formats

Decades of operational data lives in proprietary schemas with no migration path.

From assessment to sustainment, a deliberate path.

Phased modernization preserves operational continuity while eliminating legacy risk — no hard cutover, no downtime.

Explore DTSI Services

Modernized case management platform delivered by Irys DTSI

Assessment

Evaluate legacy platforms for risk, capability gaps, and migration complexity.

Architecture Design

Design a modular, cloud-native target architecture aligned to Zero Trust and the agency's operational constraints.

Migration

Move institutional data and workloads in phases, with integrity verification at every step and legacy systems still running.

Validation & Cutover

Run old and new in parallel, validate against live operations, and cut over only when the results match.

Sustainment

Monitor, patch, and improve the modernized platform with ongoing operational support after deployment.

Legacy Assessment & Analysis

Evaluate technical debt, security exposure, and migration complexity.

Modern Architecture Design

Purpose-built architecture aligned to Zero Trust and cloud-native standards.

Data Migration & Validation

Migrate institutional data with integrity verification at every step.

Cloud-Native Deployment

Infrastructure designed for scalability, resilience, and FedRAMP alignment.

Zero Trust Alignment

Security architecture built in from the foundation, not added later.

Operational Sustainment

Ongoing support, monitoring, and continuous improvement post-deployment.

Architecture modernization

Replace, don't patch.

Purpose-built modern architecture eliminates technical debt instead of adding to it. From monolithic legacy to modular, maintainable services.

From monolith to modular services. Legacy platforms decomposed into maintainable services that can be updated without downtime.
Institutional data carried forward. Decades of operational records migrated out of proprietary schemas with integrity verified at each step.
Parallel operation until cutover. Old and new systems run side by side so operations continue while the migration is validated.
