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 healthcare network faced several critical challenges that made this migration particularly complex:
EPC Group developed a comprehensive migration strategy that addressed all compliance, technical, and operational requirements:
Conducted thorough inventory of all SharePoint content, customizations, and integrations. Developed HIPAA-compliant migration architecture.
Established new information architecture and governance policies aligned with HIPAA requirements and organizational needs.
Migrated 5 pilot departments to validate approach, train change champions, and refine processes.
Executed phased migration across 200+ site collections using automated tooling and off-hours scheduling.
Delivered comprehensive training program and established ongoing support structure.
