As part of its IT Modernization roadmap, the Department of Treasury’s Office of Inspector General (TOIG) sought an experienced systems integrator to migrate and integrate its on-premises identity management, email and calendar systems, user and shared documents, and mobility management suite to an Office 365-E5 Government Community Cloud (GCC) environment. The migration required seamless integration of approximately 220 mailboxes and mobile devices, along with robust planning and change management to minimize operational disruptions.
