Practical transition of legacy systems to secure, modern cloud environments.
Structured onboarding, seamless ongoing operations
Legacy modernization is the highest-risk category of government IT work. Our approach is built around one discipline: never disrupt what's working while building what's next.
Audit the full system — codebase, architecture, business logic, integrations, and data structures. Identify what's replatformable, what needs rebuilding, and what can be retired. Output is a modernization options report with recommended path, sequencing, and risk profile.
Define the approach per system — replatform, refactor, rebuild, or replace. Map interdependencies between systems being modernized and those staying on legacy infrastructure during transition. Stakeholder alignment on approach, timeline, and success criteria before any work begins.
Modern system developed alongside the live legacy environment. Business logic reverse-engineered where documentation doesn't exist. Agency operations continue uninterrupted on existing systems throughout development.
Modern system validated against legacy outputs — not just data accuracy but workflow behavior, business rule execution, and edge case handling. The system has to work the way your agency works, not just hold the right records.
Phased cutover starting with lower-risk components. Parallel running maintained for mission-critical systems until both environments produce identical outputs. Legacy access restricted only after full agency sign-off — never unilaterally.
Legacy system retired with historical data archived to retention and NARA requirements. Post-modernization support available for optimization, enhancement, and ongoing operations as the modernized environment matures.
Compliance frameworks we work within
Legacy modernization doesn't pause your compliance obligations. Security controls, audit logging, and regulatory requirements carry over from legacy to modern environments without gaps — maintained throughout parallel running, cutover, and retirement
Modern environments built on FedRAMP-authorized platforms. Legacy ATO packages revised or replaced to reflect modernized architecture as part of the program.
Security controls mapped from legacy to modern environment with no gap in compliance posture during transition — maintained throughout parallel running and cutover phases.
Modernization to StateRAMP-authorized platforms for state agencies. Data residency and access control requirements maintained from legacy environment through modern platform.
Legacy modernization for justice, public safety, and corrections agencies with CJIS security controls maintained throughout transition. Personnel cleared per policy requirements.
Modernization of health and human services systems with HIPAA technical safeguards maintained throughout. BAAs updated to reflect new platform and vendor relationships post-modernization.
Modernization of systems handling Federal Tax Information with Pub 1075 safeguards maintained from legacy through modern platform deployment.
FISMA compliance maintained throughout the modernization lifecycle. System categorization reviewed as architecture changes. ATO implications assessed and addressed before cutover.
Internal control attestations for Consultadd's own operations available on request under NDA.
Frequently asked questions
Everything contracting officers, IT leaders, and prime capture teams routinely ask before engaging.
Yes. Some legacy systems can be moved to modern infrastructure with limited changes. Others are too outdated to replatform and need to be rebuilt from the ground up. We assess each system individually and recommend the approach that balances risk, cost, and long-term maintainability.
By building in parallel — the modern system is developed and validated alongside the legacy environment. Agency operations continue on existing systems until the replacement is proven stable and signed off. Nothing is switched off prematurely.
COBOL mainframes, PeopleSoft, JD Edwards, Lawson/Infor, Oracle Forms, and IBM mainframe systems. We profile systems directly rather than relying on outdated documentation.
Common in government environments. We reverse-engineer business logic and data models directly from the source system through codebase analysis, stakeholder interviews, and live system observation — not documentation that may be 20 years out of date.
We extract and document business rules during the assessment phase — surfacing logic that often exists only in code and institutional memory. These are validated with agency subject matter experts before being rebuilt in the modern system.
A focused replatforming of a single application can take 6–12 months. A large-scale modernization program spanning multiple interconnected systems can run 2–4 years. We scope precisely after the legacy assessment.
Both models are available. Some agencies take over operations once the modern system is stable. Others retain us for ongoing support and continuous improvement. We scope for either at the start of the engagement.
Yes. Our modernization approach is aligned to OMB IT modernization policy. We have experience supporting agencies through TMF-funded programs — from application through execution.
