How a New York based medical group migrated 65,000+ patient records to Epic in 50 days with IKS Migrate

About the medical group

A multi-specialty healthcare leader based in New York, serving over 1.6 million patients across numerous counties. With over 2,100 providers delivering primary care, specialty care, urgent care, and virtual consultations, the organization required seamless data migration to maintain their commitment to accessible, accountable care.

The stakes behind a zero-margin migration

The client faced a hard deadline to move onto Epic, with more than 65,000 patient records at risk.

Critical data gap

Electronic migration failed to capture essential pregnancy data for 65,387 patients, threatening care continuity for the most vulnerable populations.

Data chaos

Unstructured, duplicative records in Epic made critical information inaccessible to providers, risking medication errors and missed prenatal milestones.

Zero-margin timeline

The migration had to finish before Epic go-live with complete accuracy, since any delay would force providers to work across two systems at once.

A precision manual migration strategy

With IKS Migrate, we deployed a precision manual migration strategy built around four pillars.

1. Intelligent prioritization

Triaged active pregnancy patients first, ensuring zero care disruption during the transition period.

2. Precision mapping

Transformed unstructured data into searchable, structured fields (medications, allergies, problems, histories), eliminating the “data dump” problem.

3. Real-time validation

Deployed dual-EHR verification to achieve 98-99% accuracy while eliminating all duplicate records.

4. Phased execution
  1. Week 1-3: 34,431 active pregnancy patients (completed Feb 10-28)
  2. Week 4-7: 30,956 past pregnancy patients (completed Feb 28-Apr 30)
  3. Continuous quality checks throughout all phases

The impact of a clean, on-time migration

The rigorous validation process held consolidated data accuracy at 98 to 99 percent and kept appointments from being missed because of data issues. With 100 percent turnaround-time adherence and every duplicate record removed, the migration delivered data integrity beyond industry standards. Prioritizing accuracy also prevented potential medication errors and protected prenatal care continuity, backed by full compliance and a complete audit trail for regulatory peace of mind.
