- [ ] **Locations** - Core mapping feature
- [ ] **Representative Lookup** - Core advocacy feature

### 2. High Priority (Migrate Early)

- [ ] **Response Wall** - Public engagement
- [ ] **Email Sending** - Campaign functionality
- [ ] **Shift Management** - Volunteer coordination
- [ ] **Public Shift Signup** - Volunteer onboarding

### 3. Medium Priority (Migrate Mid-Phase)

- [ ] **Representative Cache** - Performance optimization
- [ ] **Postal Code Cache** - Performance optimization
- [ ] **Cuts (Territories)** - Advanced mapping
- [ ] **CSV Import/Export** - Bulk operations

### 4. Low Priority (Migrate Later)

## Workarounds for Missing Features

If you need a V1 feature not yet migrated:

### 1. Run V1 and V2 in Parallel

```bash
# Keep V1 running for specific features
docker compose -f docker-compose.v1.yml up -d

# Run V2 for new features
docker compose up -d

# Use reverse proxy to route by path:
# /v1/* → V1 apps
# /v2/* → V2 API
```

### 2. Manual Data Entry

For small datasets, manually re-enter data in V2 admin:

- Campaigns: Use Campaigns page (CRUD)
- Locations: Use Locations page or CSV import
- Shifts: Use Shifts page (CRUD)

### 3. Custom Migration Scripts

For unique V1 customizations, write custom transformation scripts:

```javascript
// scripts/migrate-custom-fields.js
const customFieldMapping = {
  v1Field: 'v2Field',
  // Add your mappings
};

// Transform and import
```

## Future Roadmap

### Planned for V2 Phase 15+

- [ ] **Multi-tenancy** - Multiple organizations per instance
- [ ] **Mobile apps** - iOS/Android native apps
- [ ] **Advanced analytics** - Campaign performance, volunteer metrics
- [ ] **AI integration** - Campaign suggestions, email drafting
- [ ] **Social media integration** - Share campaigns, auto-post
