Migrating 2 PB of file shares to Microsoft 365 for a national healthcare system

National healthcare system

Challenge

Network file shares holding 2 PB of data for more than 70 medical institutes and hospitals had to move to Microsoft 365 without disrupting providers or exposing patient data.

Approach

A multi-workstream migration planned with the business analyst teams, with Microsoft Purview Information Protection applied to healthcare and patient data and a custom engagement process designed to maximize patient safety and minimize provider impact. ShareGate and the SharePoint Migration Tool did the moving, with PowerShell and Python automation and Power BI tracking across every workstream.

Outcome

File shares moved to Microsoft 365 with data governance and security built in, and a repeatable engagement process the system could run institute by institute.

Healthcare migrations are governed by who can be interrupted and when. The engagement process was built around clinical schedules first and migration throughput second, so that no provider lost access to a working document during a shift.

Technology: Veritas DLP, ShareGate, SharePoint Migration Tool, PowerShell, Python, Power BI, OneLake data hub, Microsoft Purview.
