An EHR migration is one of the largest, riskiest projects a healthcare organization ever undertakes — and most of the pain is avoidable. Taction Software runs end-to-end EHR migrations for hospitals, health systems, and multi-site provider groups: discovery and strategy, data mapping and ETL engineering, integration cutover, parallel-run validation, phased go-live, and stabilization — engineered for zero data loss and minimal clinical downtime. Because we are healthcare software engineers who live in HL7, FHIR, and EHR integration every day, we treat your migration as an engineering problem with a reconciliation trail, not a hopeful data dump.
This page covers full platform migration — moving from one EHR to another, including workflows, integrations, and go-live. If you need pure data movement without a platform cutover — archives, warehouses, database moves — see our healthcare data migration services.

Why EHR Migrations Fail (and How We Prevent It)
Underestimated Data Volume & Complexity
Teams routinely underestimate how much data they have and how messy it is. We profile the source data up front, so volume and quality surprises happen in discovery — not during cutover.
Inadequate Clinical Workflow Discovery
A migration that moves data but breaks workflows fails clinically even if it “succeeds” technically. We map the real clinical workflows before we design anything.
Integration Footprint Mismanagement
Every EHR sits in a web of HL7 and FHIR interfaces to labs, imaging, pharmacy, billing, and HIEs. Miss one and something breaks at go-live. We audit the full integration footprint and rebuild it deliberately.
Insufficient Parallel-Run Testing
Skipping a real parallel run is how organizations discover reconciliation gaps after the old system is gone. We run and reconcile a parallel window before cutover.
Inadequate Clinician Change Management
Even a flawless data migration fails if clinicians cannot work in the new system. We plan phased go-live and clinician readiness into the project, not as an afterthought.
Our EHR Migration Methodology
Phase 1: Discovery & Migration Strategy
Source system analysis, data inventory and profiling, clinical workflow mapping, integration footprint audit, and a risk register — the phase that determines whether everything after it goes smoothly.
Phase 2: Migration Design
Data mapping and transformation rules, an integration cutover plan, a historical data strategy, and compliance and audit-trail preservation — the design that makes the engineering predictable.
Phase 3: Migration Engineering
ETL pipeline development, data quality validation, integration rebuild, and repeated test migration cycles — the build, validated again and again before it ever touches production.
Phase 4: Parallel Operation & Cutover
A parallel-run window, reconciliation reporting that proves every record landed, a phased go-live, and rollback procedures ready at every step.
Phase 5: Stabilization & Decommissioning
Post-cutover monitoring, issue triage and resolution, and orderly source-system decommissioning once the new environment is proven stable.
EHR Migration Paths We’ve Executed
We work across the major platforms and the long tail: Cerner to Epic, Allscripts to Epic or Cerner, athenahealth migration and reverse, eClinicalWorks to a modern EHR, NextGen migration, MEDITECH migration, legacy or custom EHR to a major platform, and on-premises to cloud EHR. EHR-vendor integration is a core competency — see our Epic EHR integration and Mirth Connect integration work.
Data We Migrate
We migrate the full clinical and operational record: patient demographics and master patient index, clinical documentation and notes, orders, results, and medications, allergies, problems, and immunizations, scheduling and encounters, billing and claims history, documents, images, and attachments, and — critically for compliance — audit logs.
Integration Cutover
Migration is half the job; re-establishing the integration fabric is the other half. We handle HL7 v2 interface re-establishment, FHIR API migration, lab, imaging, and pharmacy interfaces, billing and practice-management integration, and state HIE and public health reporting, so the new EHR is fully connected on day one.
Risk Management
Zero-Data-Loss Methodology
Every record is mapped, migrated, and reconciled, with reconciliation reporting that proves completeness rather than asserting it.
Clinical Downtime Minimization
We design cutover to minimize clinical downtime, using parallel operation and phased go-live to keep care running.
Compliance Continuity
We preserve audit trails and PHI safeguards throughout, so data security and compliance never lapse during the move.
Rollback Capability at Every Phase
At every phase there is a defined rollback path, so a problem is a contained step backward — not a crisis.
EHR Migration Timeline & Cost Drivers
Small Practice (1–3 Months)
Smaller migrations with contained data and a limited integration footprint typically run one to three months.
Multi-Site Practice (6–12 Months)
Multi-site groups, with more data, more integrations, and more workflows to align, generally run six to twelve months.
Health System / Hospital (12–24 Months)
Enterprise health-system migrations are major programs, typically twelve to twenty-four months, where disciplined methodology matters most. Cost is driven by data volume and quality, the number of integrations, the number of sites and users, and how much historical data must come across live.

Frequently Asked Questions
How long does an EHR migration take?
From one to three months for a small practice to twelve to twenty-four months for a health system, depending on data volume, integration footprint, number of sites, and historical-data scope. We give you a firm timeline after the readiness assessment.
Can clinical operations continue during migration?
Yes. We design for continuity using parallel operation and phased go-live, so clinicians keep working while data and integrations move, and downtime at cutover is minimized.
What about historical data we don’t need actively?
We define a historical-data strategy with you — migrating what must be live in the new system and archiving the rest in a compliant, accessible form, rather than forcing everything into the new EHR.
How do you handle PHI during migration?
PHI is protected end to end: encrypted in transit and at rest, access restricted and logged, and handled under a signed BAA. Audit trails are preserved through the migration.
Will you sign a BAA?
Yes, before any access to PHI or PHI environments. We can use our standard template or work from yours.
What if the migration fails mid-cutover?
It does not become a crisis, because we build rollback procedures at every phase and reconcile before committing. If a cutover step does not pass validation, we roll back to the last good state and resolve the issue before proceeding.
