Connect heritage and modern systems without rebuilding either.

Change the interaction between systems rather than the systems themselves, and prove migration behavior against representative journeys before committing to an irreversible cutover.

Every connection becomes a project. Every cutover becomes a bet.

Agencies run decades-old mission systems beside cloud and AI services adopted recently. Point-to-point integration pushes new logic into the applications or into project-specific plumbing. Migration testing validates components rather than complete journeys and misses the timing, data history, downstream dependencies and exceptions that determine production behavior.

A failed cutover on a state eligibility, licensing or records system is a service outage for residents and an oversight finding for the agency. Federal modernization funding increasingly requires evidence of outcome, not only of spend.

Connect, do not integrate.

Data Mediation™ translates protocols, structures and meaning at the boundary. The systems on either side continue to do their jobs. The interaction becomes the place where transformation, routing, policy and evidence are programmed, and where business and data analysts can work closer to the problem while engineers retain governance over protocols, security and performance.

1. Capture representative journeys and agree acceptance criteria.
2. Run old and new paths in shadow or dual execution.
3. Compare decisions, outputs, timing and control evidence journey by journey.
4. Move traffic progressively with explicit rollback conditions. Rollback is a configuration change, not a project.

Each stage produces a record of what was compared, what differed, when traffic moved and what rollback condition applied. The record is available to program leadership, auditors and oversight bodies without additional instrumentation. The same mediation point remains after cutover to support observability, resilience and the next change.
