The customer is a leading professional organization focused on advancing care for lung disease through education, advocacy, research, and philanthropic initiatives. They support a global community of over 15,000 pulmonary, critical care, and sleep medicine professionals working to improve the prevention, diagnosis, and treatment of upper-body diseases.

The customer largely utilized a Google Workspace environment that supported email, calendars, and collaboration tools for more than 150 users throughout the organization.

Sentinel collaborated with the customer to execute a phased migration strategy focused on both technical success and user readiness. The project began with a pilot migration before expanding to a full production deployment covering all user mailboxes and calendars. Sentinel managed migration planning, licensing validation, cutover activities, and migration execution while leveraging Quest On Demand Migration Suite and AvePoint FLY SaaS licensing to support the customer’s broader modernization goals. To help users successfully transition from Gmail to Outlook, Sentinel partnered with The Crancer Group to deliver customized Outlook training sessions, recorded resources, and ongoing guidance designed to accelerate adoption and reduce disruption.

The organization successfully migrated its messaging environment to Microsoft 365 through a structured, low-risk approach that minimized disruption to users and daily operations. The pilot-first strategy provided confidence throughout the migration, while customized Outlook training helped employees quickly adapt to new workflows. By focusing first on email and calendar services, the customer established a strong foundation for future modernization initiatives while delivering immediate value to the organization.
