Moving a health system from Cerner (now Oracle Health) to Epic is one of the most demanding programs in healthcare IT — and the hardest part is rarely Epic itself, which Epic’s own team leads. The hard part is getting your data, integrations, and clinical workflows out of Cerner Millennium cleanly and into Epic without losing anything or disrupting care. That is exactly where Taction Software fits: we handle the Cerner-side extraction, the data migration engineering, and the integration cutover, working alongside your Epic implementation team — with a zero-data-loss methodology and a reconciliation trail that proves it.
This page covers the Cerner-to-Epic path specifically. For other platform moves or a general overview, see our EHR migration services.

Why Health Systems Are Moving From Cerner to Epic
Post-Oracle Acquisition Strategic Considerations
Following Oracle’s acquisition of Cerner, many health systems are re-evaluating their long-term EHR strategy and roadmap confidence. For some, that evaluation ends in a decision to move to Epic.
Epic Market Position & Roadmap Confidence
Epic’s market position, integrated suite, and product roadmap give some organizations more long-term confidence — a major factor in a decision this expensive and long-lived.
Integration & Interoperability Differences
Differences in how the platforms handle integration and interoperability influence the decision, especially for systems with a large, complex interface footprint.
Workforce & Talent Availability
The availability of Epic-experienced clinical and IT talent in the market is a practical consideration for systems planning for the next decade.
What Makes Cerner-to-Epic Migrations Different
Cerner Data Model Complexity
Getting data out of Cerner cleanly means working with the Millennium architecture, the Cerner Open Engine interface layer, and PowerChart data structures — and understanding where the clinically important data actually lives.
Epic Implementation Requirements
The target side means mapping into Epic’s Chronicles operational data model and Clarity reporting database, aligned to your Epic module configuration — work that has to match how Epic is being built for you.
Integration Differences
The interface fabric changes shape: Cerner HL7 and FHIR endpoints on one side, Epic’s bridges, App Orchard / Connection Hub, and integration tooling on the other. We rebuild that fabric deliberately, drawing on our Epic EHR integration, HL7, and FHIR practices.
Our Cerner-to-Epic Migration Methodology
Phase 1: Cerner Environment Discovery
We profile the Cerner environment — data, interfaces, custom builds, and reports — so the full scope is understood before design begins.
Phase 2: Epic Implementation Coordination
We coordinate with your Epic implementation team so our data and integration work aligns precisely with how Epic is being configured and when it goes live.
Phase 3: Data Migration Engineering
We build and validate the ETL from Cerner to Epic, with repeated test migration cycles and data-quality validation, drawing on our custom healthcare software development engineering.
Phase 4: Integration Cutover
We re-establish the interface fabric in Epic — labs, imaging, pharmacy, HIE, public health, and third-party apps — using Mirth Connect and Epic’s integration tooling.
Phase 5: Phased Go-Live & Stabilization
We support a phased go-live with reconciliation reporting, rollback paths, and post-cutover stabilization until the environment is proven stable.
Data We Migrate
We migrate the full record from Cerner to Epic: patient master index and demographics, clinical documentation, orders, results, and medications, scheduling and visit history, billing and revenue-cycle data, and — critically for compliance — audit logs and compliance records.
Integration Migration
We rebuild every interface the new environment needs: lab and imaging interfaces, pharmacy integration, HIE connections, public health reporting, and third-party application integration, so Epic is fully connected at go-live.
Clinical Workflow Continuity
Order Set & Documentation Template Translation
We translate order sets and documentation templates so clinicians find the workflows they depend on in Epic.
Clinical Decision Support Migration
We carry clinical decision support logic across so safety and guidance do not regress in the new system.
Reporting & Quality Measure Continuity
We preserve reporting and quality-measure continuity, including the move from Cerner CCL reporting to Epic’s Clarity, so your reporting does not go dark after cutover.
Timeline & Investment for Cerner-to-Epic Migration
Typical Range: 12–24 Months
A health-system Cerner-to-Epic migration is typically a twelve-to-twenty-four-month program, paced largely by the Epic implementation it runs alongside.
Phase-Based Cost Structure
Cost is structured by phase — discovery, engineering, integration, and go-live — and driven by environment size, integration footprint, and the volume of custom Cerner builds and reports to translate.
Internal Resource Requirements
We are explicit up front about the internal clinical, IT, and data resources the program needs from you, so staffing is planned rather than discovered mid-project.

Frequently Asked Questions
How long does a Cerner to Epic migration take?
For a health system, typically twelve to twenty-four months, paced by the Epic implementation it runs alongside and by your environment’s size, integration footprint, and custom-build volume. We give a firm timeline after the strategy briefing.
Are you Epic-certified or in App Orchard?
Epic’s build is led by Epic and Epic-credentialed resources, and Epic controls module certification for that work. Our role is the Cerner-side extraction, data migration engineering, and integration — and we develop to Epic’s integration program (App Orchard / Connection Hub) where your project requires it. Tell us your specifics on the briefing and we will confirm exactly how our team’s credentials map to your engagement.
Will Epic’s own implementation team work alongside you?
Yes. Epic typically leads the Epic configuration and go-live; we work alongside that team, owning the source-system extraction, data conversion, and integration cutover, and coordinating tightly so the two streams stay in lockstep.
What about Cerner add-on modules?
We inventory your Cerner add-on modules in discovery and plan how each one’s data and workflow are handled — migrated, replaced by an Epic equivalent, or archived — rather than discovering them at cutover.
How do you handle CCL reports and custom Cerner builds?
Custom Cerner builds and CCL (Cerner Command Language) reports are a common source of migration risk. We catalog them in discovery, then translate the ones you still need into Epic’s equivalents — including Clarity-based reporting — and retire the rest deliberately.
