   - Convert URL patterns to Fess regex patterns
   - Set up LabelType (access control labels) if defined

**Step 3: Verify Imported Configurations**

After import, verify:
- **Crawler > Web**: Check web crawling configurations
- **Crawler > File**: Check file crawling configurations (SMB, FTP)
- **System > General**: Verify URL patterns and filters

### Key Design Patterns

- **Factory**: `CrawlerClientFactory`, `ExtractorFactory` - protocol/format-specific component selection
- **Strategy**: `CrawlerClient`, `Extractor`, `Transformer` - pluggable implementations
