• Cutover & Hypercare: Lead cutover events (domain/DNS changes, final syncs, validations) to successfully switch over users and services. Provide post-migration hypercare, addressing user issues and stabilizing the environment.
• Collaboration & Coordination: Work closely with the Migration Architect, OCM leads, and device teams to align technical steps with user communications, training, and any Intune device updates. Mentor junior engineers and keep stakeholders informed on progress.
