Healthcare software modernization

Modernize Legacy Healthcare Software Without a Big-Bang Rewrite

Preserve the workflows and data that still work. Replace aging interfaces, architecture, integrations, and infrastructure in controlled phases using modern web technology, APIs, FHIR, cloud services, automation, and AI where they create real value.

Modernization, not replacement for its own sake

The goal is to reduce risk while increasing the rate of change

Legacy healthcare systems often contain years of valuable workflow knowledge. Rewriting everything at once can destroy that knowledge while introducing new operational risk.

We start by identifying what must remain stable, where the architecture blocks growth, which manual steps are expensive, and which components can be isolated behind new interfaces. Modernization then becomes a sequence of controlled product releases rather than one giant migration event.

What can be modernized

Upgrade the parts that create the most friction

A modernization program can target one layer or progressively reshape the entire product.

UX

Modern Web & Mobile Experience

Replace dated screens with React and modern mobile experiences while keeping existing backend workflows operational during transition.

API

API & Service Layer

Put stable APIs around legacy functions, separate business logic from the user interface, and create clear contracts for new modules and integrations.

FHIR

FHIR-Native Data Foundation

Introduce a standards-based clinical model where it improves interoperability, data portability, longitudinal workflows, or future application development.

☁

Cloud & DevOps

Containerize services, automate deployment, improve environment consistency, observability, backups, scaling, and production operations.

↔

Interoperability

Replace brittle one-off interfaces with reusable FHIR, HL7, API, HIE, SFTP, and workflow integration patterns.

AI

AI-Enabled Workflows

Add document intelligence, assisted documentation, natural-language interaction, extraction, classification, or review workflows without placing AI outside the operational context.

DATA

Data Migration & Analytics

Map legacy schemas, normalize key data, preserve provenance, build reconciliation, and create analytics-ready datasets without losing operational history.

AUTO

Workflow Automation

Remove repetitive search, copy, upload, routing, status-checking, and exception-handling steps while preserving human review where it matters.

Phased modernization

A safer path from legacy architecture to a modern healthcare platform

Each phase should produce usable value while reducing the dependency on the old system.

01

Understand & Stabilize

Map users, workflows, integrations, data ownership, known failures, security constraints, and the components that cannot be disrupted.

02

Create Boundaries

Introduce APIs, events, queues, or integration adapters around high-value legacy capabilities so new modules do not depend directly on internal implementation details.

03

Modernize the Data Layer

Define canonical models, FHIR mappings where useful, migration logic, identifiers, validation, reconciliation, and ownership between old and new systems.

04

Replace Workflows Incrementally

Move one provider, patient, operational, or administrative workflow at a time to modern services and interfaces while tracking exceptions and adoption.

05

Retire Legacy Components

Only decommission modules after the replacement is proven, monitored, documented, and operationally owned.

Where Medplum can fit

Use Medplum as the FHIR-native foundation when that simplifies the future state.

A legacy modernization project does not have to move everything into Medplum. It can introduce Medplum selectively as a modern clinical data, application, or workflow foundation while existing systems continue running.

Explore Medplum Development →
FHIR clinical data layerNormalize selected clinical and operational data around a modern standards-based model.
New provider applicationBuild modern workflows while the legacy backend is progressively decomposed.
New patient experienceExpose controlled modern APIs without rewriting the entire legacy product first.
Migration destinationMove legacy clinical data in stages with validation and reconciliation.
Avoid replacing one lock-in with another

The modernized product should remain under your control.

For custom modernization engagements, we can work in client-owned repositories and client-controlled infrastructure so the organization retains direct access to the system it is investing in.

Our intended commercial model is client ownership of the project-specific code and IP created for the modernization program under the engagement agreement, with clear separation of open-source, third-party, and pre-existing reusable components.

Client-owned source repositoryTransparent access to the evolving codebase, not a black-box deliverable.
Client-controlled cloudDeploy into the organization’s environment when appropriate.
Migration documentationMappings, cutover plans, architecture decisions, interfaces, and operational runbooks.
Internal-team transitionRetain us long term or move ownership progressively to your own engineers.

Modernization assessment

Show us the system you are reluctant to rewrite.

We can review the relevant architecture and workflow at a high level, identify practical modernization boundaries, and suggest a phased path that protects current operations.
