Healthcare Provider Migrates 50M+ Patient Records with Zero Downtime

Our client is a leading healthcare technology provider serving over 2,000 clinics and hospitals across the United States. With 15 million active patients and processing 500,000+ clinical encounters daily, they are at the forefront of digital health transformation in the post-pandemic healthcare landscape.

The organization manages comprehensive patient data including medical histories, lab results, imaging, prescriptions, and insurance information across multiple specialties. Their legacy infrastructure, built over 20 years, consisted of 12 different systems that needed consolidation into a unified platform.

The healthcare provider faced critical challenges with their fragmented data infrastructure that was hindering patient care quality and operational efficiency.

We designed and executed a comprehensive data migration strategy leveraging Salesforce Health Cloud with custom-built migration tools and real-time synchronization capabilities to ensure zero downtime.

Our 16-week implementation followed a meticulous approach ensuring data integrity, compliance, and zero disruption to patient care operations.

• Weeks 1-3: Assessment & Planning - Analyzed 12 legacy systems, mapped 2,500+ data fields, identified transformation rules, and designed migration architecture
• Weeks 4-6: Infrastructure Setup - Built HIPAA-compliant cloud infrastructure, established encrypted pipelines, and configured Health Cloud environment
• Weeks 7-9: Data Cleansing - Processed 50M records through deduplication engine, standardized formats, and enriched missing data elements
• Weeks 10-12: Pilot Migration - Migrated 5M records for 200 pilot clinics, validated accuracy, and refined transformation logic
• Weeks 13-14: Full Migration - Executed parallel migration of remaining 45M records with real-time sync maintaining operational continuity
• Weeks 15-16: Validation & Cutover - Comprehensive data validation, user acceptance testing, and seamless production cutover with zero downtime

The migration transformed the healthcare provider's data infrastructure, enabling superior patient care while maintaining perfect compliance and operational continuity.
