Key Responsibilities

End-to-End Migration: Lead the parallel upgrade and side-by-side migration of legacy on-premises servers to modern operating systems within a highly available VMware environment.

Infrastructure Virtualization: Manage, optimize, and provision resources within the VMware vSphere/ESXi infrastructure to support the newly migrated workloads.

Role-Specific Upgrades: Plan and execute zero-to-minimal downtime migrations for specialized server roles, ensuring all configurations, permissions, and dependencies are seamlessly transferred.

Testing and Validation: Perform pre- and post-migration checks, validate application and service functionality, and confirm system stability, performance, access, and security settings before production cutover.

Patch and Lifecycle Management: Plan and implement approved Windows Server and VMware ESXi/vCenter patches and updates during the migration activities; validate updates in staging where available and coordinate deployment windows to minimize disruption.

Performance and Capacity Optimization: Monitor Windows and VMware resource utilization, review CPU, memory,

storage, and capacity trends, and recommend virtual machine right-sizing and resource-allocation improvements.

PowerShell Automation: Create and maintain PowerShell scripts to streamline routine administration, configuration checks, patching tasks, and system health reporting.

Documentation and Change Coordination: Maintain accurate technical documentation, standard operating procedures,

migration plans, rollback steps, and environment diagrams. Coordinate planned changes and cutovers with relevant technical teams and stakeholders.
