# Organization Icons Migration Guide

This guide shows how to migrate from the current sector/subtype system to the new categorization system while maintaining icon compatibility.

## Migration Strategy

### Phase 1: Data Preparation

1. **Analyze current data**: Map existing sector/subtype combinations to new categories
2. **Create migration mapping table**: Document how each organization will transition
3. **Update database schema**: Add new categorization fields while keeping legacy fields

### Phase 2: Icon System Updates

1. **Update icon mapping function**: Modify `getLucideIconForSubtype()` to work with new system
2. **Create fallback logic**: Ensure backward compatibility during transition
3. **Test icon rendering**: Verify all combinations display correctly

### Phase 3: UI Updates

1. **Update filter interfaces**: Implement new filtering based on service categories
2. **Modify search logic**: Support multi-dimensional filtering
3. **Update admin interfaces**: Allow categorization using new system

## Implementation Code Example

```typescript
// New categorization interface
interface OrganizationCategory {
  primarySector: PrimarySector;
  businessTypes: BusinessType[];
  serviceCategories: ServiceCategory[];
}

// Migration function
function migrateOrganizationCategory(
  legacySector: string,
  legacySubtype: string
): OrganizationCategory {
  const mapping = LEGACY_TO_NEW_MAPPING[`${legacySector}/${legacySubtype}`];
  return {
    primarySector: mapping.primarySector,
    businessTypes: mapping.businessTypes,
    serviceCategories: mapping.serviceCategories,
  };
}

// Updated icon selection logic
function getIconForOrganization(category: OrganizationCategory): LucideIcon {
  // Priority: Service Category > Business Type > Primary Sector
  const serviceCategoryIcon = getServiceCategoryIcon(category.serviceCategories[0]);
  if (serviceCategoryIcon) return serviceCategoryIcon;

  const businessTypeIcon = getBusinessTypeIcon(category.businessTypes[0]);
  if (businessTypeIcon) return businessTypeIcon;

  return getPrimarySectorIcon(category.primarySector);
}
```

## Backward Compatibility

### During Migration

- Keep legacy sector/subtype fields in database
- Add new categorization fields alongside existing ones
- Icon function checks new system first, falls back to legacy mapping

### Post-Migration

- Legacy fields can be deprecated after full transition
- Update all data entry points to use new categorization
- Clean up legacy mapping code

## Testing Checklist

- [ ] All current organizations display with appropriate icons
- [ ] New categorization fields work correctly
- [ ] Filtering by service categories functions properly
- [ ] Search results include relevant organizations
- [ ] Admin interface supports new categorization
- [ ] Performance impact is minimal
- [ ] Mobile responsiveness maintained

## Rollback Plan

If issues arise during migration:

1. **Immediate rollback**: Switch back to legacy icon mapping
2. **Data preservation**: Keep new categorization data for future migration
3. **Staged approach**: Migrate in smaller batches to isolate issues
4. **User communication**: Inform users of temporary categorization changes
