Known Issues & Limitations

Current Limitations

1. BusLogic Controllers: Legacy BusLogic SCSI requires manual VMware reconfiguration
   • Workaround: Change to LSI Logic in VMware before migration
   • Documentation: BusLogic Auto-Fix
2. Linked Clones: VMware linked clones not supported
   • Workaround: Consolidate snapshots before migration
   • Documentation: VMDK Inspector
3. Encrypted Disks: BitLocker/LUKS requires pre-decryption
   • Workaround: Decrypt before migration, re-encrypt after
   • Documentation: Security Best Practices

Test Environment Blockers

• OpenShift CRC: Disk pressure issues on local testing (resolved in cloud deployments)
• Nested Virtualization: Performance limitations in nested environments
