Migration Planning
Assessment Phase
• Inventory all VMs and workloads
• Document dependencies
• Evaluate storage requirements
• Network architecture review
• Licensing audit
Planning Phase
• Define migration strategy
• Create testing environment
• Develop rollback procedures
• Schedule maintenance windows
• Train IT staff
Execution Phase
• Pilot migration (non-critical VMs)
• Validate functionality
• Phased production migration
• Monitor performance
• Documentation updates
Migration Tools & Methods
| Method | Description | Complexity |
|---|---|---|
| P2V Conversion | Physical to Virtual migration | Medium |
| V2V Migration | VMware to Proxmox conversion using qemu-img | Medium |
| Storage Migration | Copy/convert VM disks between platforms | Low |
| Application Rebuild | Deploy fresh VMs, migrate application data | High |
