Project Overview

Cross-platform workload migration and validation

This project simulated a production-style migration of a Windows Server workload from VMware Workstation to Proxmox VE. The source virtual machine included Windows Server, networking, virtual storage, and SQL Server Express.

The migration required source-system validation, OVF export, virtual-disk import, hardware reconfiguration, driver changes, network recovery, and application testing in the destination environment.

The completed migration demonstrated how infrastructure workloads can be transferred between virtualization platforms while maintaining service availability and data integrity.

Migration Architecture

Source-to-destination workflow

Phase 1VMware Source VM

Phase 2Source Validation

Phase 3OVF Export

Phase 4Proxmox Import

Phase 5Destination Validation

The source Windows Server workload was first documented and tested in VMware Workstation. It was then exported as an OVF appliance, imported into Proxmox VE, reconfigured for the destination hypervisor, and validated against the original baseline.

Migration Workflow

Major tasks completed

✓Built and configured the source Windows Server virtual machine in VMware Workstation.
✓Installed VMware Tools and validated operating-system functionality.
✓Installed SQL Server Express and confirmed database-service availability.
✓Documented the source virtual-machine hardware, networking, storage, and application state.
✓Prepared the virtual machine for migration and performed a final source validation.
✓Exported the source virtual machine as an OVF appliance.
✓Transferred the exported appliance into the Proxmox VE environment.
✓Imported the virtual disks and created the destination Proxmox virtual machine.
✓Reconfigured CPU, memory, storage controllers, firmware, and virtual network adapters.
✓Installed VirtIO drivers and removed VMware-specific dependencies where required.
✓Restored network connectivity and validated application functionality.
✓Compared source and destination results and documented the completed migration.

Validation

Business Value

Platform flexibility and migration readiness

Cross-platform migration gives organizations greater flexibility when modernizing infrastructure, reducing licensing costs, replacing legacy virtualization platforms, or consolidating workloads. A documented validation process also reduces risk and helps confirm that operating systems, networking, applications, and data continue functioning after migration.
