Overview

A leading healthcare network operating across multiple states needed to modernize their collaboration infrastructure by migrating from an aging SharePoint 2013 on-premises environment to SharePoint Online. The migration had to maintain HIPAA compliance, ensure zero downtime for clinical operations, and preserve 10+ years of critical medical documentation.

The Challenge

The healthcare network faced several critical challenges that made this migration particularly complex:

  • Legacy SharePoint 2013 environment with extensive customizations and workflows
  • Strict HIPAA compliance requirements for all patient-related data
  • Zero tolerance for downtime due to 24/7 clinical operations
  • Complex permission structures across 200+ site collections
  • 10 million+ documents requiring metadata preservation
  • Integration with Epic EHR system and other clinical applications

Our Solution

EPC Group developed a comprehensive migration strategy that addressed all compliance, technical, and operational requirements:

1

Phase 1: Assessment & Planning

Conducted thorough inventory of all SharePoint content, customizations, and integrations. Developed HIPAA-compliant migration architecture.

2

Phase 2: Governance Framework

Established new information architecture and governance policies aligned with HIPAA requirements and organizational needs.

3

Phase 3: Pilot Migration

Migrated 5 pilot departments to validate approach, train change champions, and refine processes.

4

Phase 4: Wave Migrations

Executed phased migration across 200+ site collections using automated tooling and off-hours scheduling.

5

Phase 5: Training & Adoption

Delivered comprehensive training program and established ongoing support structure.
