| `on_ge_network` | ENUM('Yes','No','N/A') | Whether device is on GE network |
| `asset_criticality` | ENUM('High','Medium','Low','N/A') | Asset criticality level |
| `jump_box` | ENUM('Yes','No','N/A') | Whether device is a jump box |
| `mft` | ENUM('Yes','No','N/A') | Managed File Transfer status |
| `gecoreload` | ENUM('Yes','No','N/A') | GE Core Load status (already existed in compliance) |

## Migration Steps

### 1. Pre-Migration Analysis

**machines table:**
- All 7 columns existed in machines table
- **0 machines** had any data in these columns (all NULL)

**compliance table:**
- Had 406 compliance records
- Only `gecoreload` column existed (with 172 records populated)
- Missing: systemname, devicedescription, on_ge_network, asset_criticality, jump_box, mft

**ASP code analysis:**
- **0 ASP files** reference any of these columns
- No code changes required

### 2. Migration Actions

**Added to compliance table:**
```sql
ALTER TABLE compliance ADD COLUMN systemname TEXT NULL;
ALTER TABLE compliance ADD COLUMN devicedescription VARCHAR(1000) NULL;
ALTER TABLE compliance ADD COLUMN on_ge_network ENUM('Yes','No','N/A') NULL;
ALTER TABLE compliance ADD COLUMN asset_criticality ENUM('High','Medium','Low','N/A') NULL;
ALTER TABLE compliance ADD COLUMN jump_box ENUM('Yes','No','N/A') NULL;
ALTER TABLE compliance ADD COLUMN mft ENUM('Yes','No','N/A') NULL;
```

**Removed from machines table:**
```sql
ALTER TABLE machines DROP COLUMN systemname;
ALTER TABLE machines DROP COLUMN devicedescription;
ALTER TABLE machines DROP COLUMN on_ge_network;
ALTER TABLE machines DROP COLUMN asset_criticality;
ALTER TABLE machines DROP COLUMN jump_box;
ALTER TABLE machines DROP COLUMN mft;
ALTER TABLE machines DROP COLUMN gecoreload;
```

### 3. Post-Migration Verification

**compliance table:**
- Now has 20 columns (was 14, added 6 new columns)
- All 7 compliance columns present ✅

**machines table:**
- Now has 31 columns (was 38, removed 7 columns)
- No compliance columns remaining ✅

**Data integrity:**
- No data loss (all columns were NULL in machines table)
- Existing gecoreload data (172 records) preserved in compliance table ✅

---

## Impact Analysis

### Database Schema

**Before:**
- machines table: 38 columns (including 7 compliance columns)
- compliance table: 14 columns

**After:**
- machines table: 31 columns (no compliance columns)
- compliance table: 20 columns (all compliance data)

### Application Code

**Changes Required:** NONE ✅

- No ASP files referenced these columns
- No views or stored procedures affected
- No front-end pages affected

---

## Benefits

1. **Data Organization**
   - All compliance-related data now in dedicated compliance table
   - machines table focused on hardware/asset data only

2. **Cleaner Schema**
   - Removed 7 unused columns from machines table
   - Better separation of concerns

3. **Future Maintenance**
   - Compliance data easier to manage in one place
   - Simpler queries for compliance reporting

## Related Migrations

This migration is part of ongoing cleanup efforts:

1. **Network Columns** (pending)
   - ipaddress2, ipaddress3, macaddress2, macaddress3, vlan
   - These are also unused and can be removed (ipaddress1 is used by printers)

2. **Phase 1 Legacy** (pending)
   - pctypeid column still exists (235 PCs have data)
   - Needs migration to use machinetypeid instead
