## Migration Method

### Backup/Restore Process

Used `vzdump` and `pct restore` to migrate VMs:

1. **Backup:** Created backups on r630-02 using `vzdump` to local storage
2. **Restore:** Restored backups to r630-01 with target storage specification
3. **Verification:** Confirmed VMs on target node
4. **Cleanup:** Removed original VMs from source

**Commands:**
```bash
# Backup
vzdump <vmid> --storage local --compress gzip --mode stop

# Restore
pct restore <vmid> /var/lib/vz/dump/vzdump-lxc-<vmid>-*.tar.gz \
    --storage <target-storage> \
    --target r630-01

# Cleanup
pct destroy <vmid>  # on source node
```

## Storage Distribution

### r630-01 Storage Usage

| Storage | Type | Used | Available | VMs |
|---------|------|------|-----------|-----|
| thin1 | lvmthin | 96 GB | 112 GB | VMIDs 100-130 |
| local | dir | 210 GB | 326 GB | VMIDs 7800-7811 |
| **Total** | | **306 GB** | **438 GB** | **12 containers** |

## Issues Resolved

### Storage Configuration Mismatch

**Problem:**
- Direct migration failed due to storage volume group mismatch
- thin1 on r630-02 uses VG `thin1`, but config said `pve`
- thin1 on r630-01 uses VG `pve`

**Solution:**
- Used backup/restore method which bypasses storage configuration issues
- Allows storage conversion during restore (thin4→local, thin1→thin1)

---

## Verification

### Pre-Migration
- ✅ All 12 VMs verified on r630-02
- ✅ Storage capacity confirmed (944 GB available)
- ✅ All VMs in stopped state

### Post-Migration
- ✅ All 12 VMs verified on r630-01
- ✅ No VMs remaining on r630-02 for these VMIDs
- ✅ Storage usage confirmed
- ✅ VMs configured correctly

## Migration Script

**Script:** `scripts/migrate-vms-backup-restore-final.sh`

**Features:**
- Automated backup/restore for all VMs
- Error handling and verification
- Progress reporting
- Automatic cleanup

---

## Next Steps

1. ✅ **Migration Complete**
2. ⏳ **Verify VM functionality** - Start VMs and verify services
3. ⏳ **Monitor storage usage** - Track thin1 and local storage
4. ⏳ **Cleanup backups** - Remove backup files if no longer needed
5. ⏳ **Update documentation** - Document final VM locations

---

## Key Learnings

1. **Backup/Restore Method:** Reliable when storage configurations don't match
2. **Storage Conversion:** Proxmox automatically converts storage types during restore
3. **Verification:** Always verify VMs on target before removing from source
4. **Storage Planning:** Separate storage pools (thin1 vs local) for different VM groups
