Case Study: IPSEN achieves zero-downtime Google Workspace to Microsoft 365 migration with Cloudiway

IPSEN migrates 5,800 users and 17 TB to Microsoft 365 with Cloudiway

Ipsen, a global pharmaceutical company, faced the challenge of migrating 5,800 users and 17TB of data from Google Workspace to Microsoft 365, a type of migration that was uncharted territory in 2013. They needed to move all data types—including email, Drive files, calendars, and contacts—with zero downtime and no business disruption while preserving permissions and calendar coexistence. Ipsen partnered with vendor Cloudiway, which developed a custom migration solution for this project.

Cloudiway implemented a solution featuring delta synchronization and a single platform to manage all data types, ensuring a seamless transition with complete data integrity and zero downtime. The migration was a success, described as a "non-event" for employees, and it set a new standard as the first-ever solution for migrating Google Drive to OneDrive with full permission preservation.
