## Step 5: Deployment Commands

```bash
# 1. Connect to production server
ssh your_server

# 2. Backup current files
cd /var/www/html/dashboard-v2
tar -czf backup_$(date +%Y%m%d_%H%M%S).tar.gz api.php js/ index.html

# 3. Run database migration
mysql -u your_user -p shopdb < /path/to/dualpath_migration.sql

# 4. Copy updated files
# Copy all PHP and JS files from development to production

# 5. Clear any caches
# If using opcache
service php-fpm reload

# 6. Test the deployment
curl http://your_server/dashboard-v2/api.php?action=getDualPathAssignments
```

## Step 6: Verification Tests

1. **Check API endpoints:**
```bash
# Test new DualPath endpoint
curl "http://your_server/dashboard-v2/api.php?action=getDualPathAssignments"
```

2. **Check Machines page:**
- Verify machines table shows DualPath indicators
- Check that secondary machines show link icon

3. **Check Assets page:**
- Verify DualPath badge appears for enabled PCs

4. **Check Summary page:**
- Verify Shopfloor Applications chart loads

5. **Check Machine Details:**
- Open details for a DualPath-enabled PC
- Verify DualPath section appears with warnings

## Step 7: Post-Deployment

1. **Monitor error logs:**
```bash
tail -f /var/log/apache2/error.log
tail -f /var/log/mysql/error.log
```

2. **Run PowerShell script on a test PC:**
- Verify GE registry and DualPath data saves correctly

3. **Manual DualPath assignment test:**
- Use API to assign a secondary machine
- Verify it appears in machines table

## Rollback Plan

If issues occur:

```bash
# 1. Restore database tables (if needed)
mysql -u your_user -p shopdb
DROP TABLE IF EXISTS pc_dualpath_assignments;
DROP VIEW IF EXISTS vw_machine_assignments;

# 2. Restore backed up files
cd /var/www/html/dashboard-v2
tar -xzf backup_[timestamp].tar.gz

# 3. Reload services
service apache2 reload
service php-fpm reload
```

## Notes

- The boolean conversion fix in api.php is critical for PowerShell data
- DualPath assignments are manual until patterns are established
- Monitor the first few PCs that report DualPath status
- Consider creating a DualPath management UI page in future

## Support

If issues arise:
1. Check PHP error logs
2. Verify database migration completed
3. Clear browser cache
4. Test API endpoints directly
