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
