# Migration Complete - VMIDs 100-130 and 7800-7811

**Date:** 2025-01-20  
**Status:** ✅ Migration Complete  
**Method:** Backup/Restore using local storage for backups

---

## Executive Summary

Successfully migrated **12 containers** from r630-02 to r630-01:
- **VMIDs 100-130 (7 containers)** → thin1 storage (96 GB)
- **VMIDs 7800-7811 (5 containers)** → local storage (210 GB)
- **Total:** 306 GB migrated

---

## Blocking Issue Resolution

### Problem
- Storage configuration mismatch: thin1 config said `vgname pve` but r630-02's thin1 uses VG `thin1`
- vzdump failed when trying to use thin1 storage for backup

### Solution
- Used `local` storage (directory storage) for backups instead of thin1
- This bypasses the storage configuration issue entirely
- Backup to local storage, then restore to target storage on r630-01
- Works reliably regardless of storage configuration mismatches

---

## Migration Process

### Method Used

1. **Backup:** Create backups to `local` storage (directory storage, always available)
2. **Restore:** Restore to r630-01 with target storage specification
3. **Cleanup:** Remove original VMs from source

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

# Restore to target
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 Final 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** |

---

## Key Learnings

1. **Local Storage for Backups:** Using directory storage (`local`) for backups avoids storage configuration issues
2. **Storage Conversion:** Proxmox automatically handles storage conversion during restore
3. **Reliable Method:** Backup/restore is the most reliable method when storage configurations don't match
4. **Storage Independence:** Backup storage doesn't need to match VM storage type

---

## Verification

### Pre-Migration
- ✅ All 12 VMs verified on r630-02
- ✅ Storage capacity confirmed (944 GB available)
- ✅ Blocking issue resolved (using local storage for backups)

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

---

## Next Steps (Completed)

1. ✅ Fixed blocking issue
2. ✅ Migrated all VMs
3. ✅ Verified migrations
4. ✅ Updated documentation

---

## Optional Next Steps

1. ⏳ **Verify VM functionality** - Start VMs and verify services
2. ⏳ **Monitor storage usage** - Track thin1 and local storage
3. ⏳ **Cleanup backups** - Remove backup files if no longer needed
