Migration Considerations
Technical Challenges
- vTPM migration: Currently impossible VMware → Proxmox
- vSAN-backed VMs: Cannot be directly imported
- Encrypted VMs: Must remove encryption before migration
- Snapshots: Must consolidate before migration
- API dependencies: Proprietary integrations require rebuilding
Recommended Approach
- Inventory - Document all VMs, dependencies, and integrations
- Categorize - Identify migration complexity per workload
- Pilot - Test migration with non-critical workloads
- Phase - Plan migration in waves over 12-24 months
- Validate - Verify application functionality post-migration
