Esta separación de partes, y ser un "microframework" que podría extenderse para cubrir exactamente lo que se necesita, fue una funcionalidad clave que quise mantener.

Dada la simplicidad de Flask, parecía una buena opción para construir APIs. Lo siguiente a encontrar era un "Django REST Framework" para Flask.

### 3. Backup Existing System

Before migration:

1. Export current search configurations
2. Backup existing indices and data
3. Document custom integrations and API endpoints
4. Save user access control settings

## Migration Methods

### Google Search Appliance (GSA) / Google Mini

Fess provides comprehensive GSA migration support through configuration import and API compatibility.
