• Develop practical migration approaches that address mailbox, file, collaboration, identity, device, and security workloads with minimal business disruption.
• Support pilot migrations, user readiness activities, cutover events, and post-migration issue resolution.
• Create and maintain clear technical documentation, runbooks, configuration records, and transition materials for implemented solutions.
• Participate in sales discovery to validate requirements, shape scope, identify assumptions and risks, and recommend migration strategies for Modern Work engagements.
