The Windows Server Migration Engineer will support the delivery of a large-scale server upgrade Programme, focused on migrating business‑critical services from Windows Server 2012 to modern Windows Server platforms. You will work closely with Infrastructure teams, Application Support teams, Managed Service Providers, and business stakeholders to plan, coordinate, validate, and support migration activities throughout the project lifecycle.
