Day-to-day tasks will include executing mailbox, distribution list, and resource mailbox migrations using Google Workspace migration tools, managing mail flow cutover with DNS updates and coexistence planning, and providing client configuration support for Outlook and mobile devices. Post-migration, the engineer will decommission Exchange servers, update internal documentation, and deliver knowledge transfer sessions and final documentation to IT staff.
