+---
+
+## 🔄 **How It Works**
+
+### Configuration-Based Switching
+
+**Use RAG:**
+```bash
+export INTENT_DETECTION_CLIENT=rag
+export RAG_SERVER_URL=https://your-rag-server.com
+export RAG_SERVER_API_KEY=your-api-key
+```
+
+**Use Dialogflow:**
+```bash
+export INTENT_DETECTION_CLIENT=dialogflow
+```
+
+### Request Flow
+
+```
+User Request
+    ↓
+DLP Obfuscation
+    ↓
+ConversationManagerService / NotificationManagerService
+    ↓
+IntentDetectionService (interface)
+    ↓
+    ├─→ DialogflowClientService (if client=dialogflow)
+    └─→ RagClientService (if client=rag)
+            ↓
+            RagRequestMapper
+            ↓
+            WebClient → RAG Server
+            ↓
+            RagResponseMapper
+    ↓
+DetectIntentResponseDTO
+    ↓
+Persist to Memorystore + Firestore
+    ↓
+Response to User
+```
+

+## 🚀 **Ready to Deploy**
+
+### Prerequisites
+
+1. **RAG Server Running**
+   - Implement API per `docs/rag-api-specification.md`
+   - Endpoint: `POST /api/v1/query`
+
+2. **Environment Variables Set**
+   ```bash
+   INTENT_DETECTION_CLIENT=rag
+   RAG_SERVER_URL=https://your-rag-server.com
+   RAG_SERVER_API_KEY=your-api-key  # optional
+   ```
+
+### Deployment Steps
+
+1. **Build Application**
+   ```bash
+   mvn clean package
+   ```
+
+2. **Run Tests**
+   ```bash
+   mvn test
+   ```
+
+3. **Deploy to Dev**
+   ```bash
+   # Deploy with RAG enabled
+   kubectl apply -f deployment-dev.yaml
+   ```
+
+4. **Verify Logs**
+   ```
+   ✓ Intent detection configured to use RAG client
+   RAG Client initialized successfully with endpoint: https://...
+   ```
+
+5. **Test Endpoints**
+   ```bash
+   # Test conversation
+   curl -X POST http://localhost:8080/api/v1/dialogflow/detect-intent \
+     -H "Content-Type: application/json" \
+     -d '{"message": "Hola", "user": {"telefono": "123"}}'
+   ```
+

+
+## 📈 **Migration Phases**
+
+### Phase 1: Development (1 week) - **READY NOW**
+- ✅ Code complete
+- ✅ Tests passing
+- ✅ Documentation ready
+- 🎯 Deploy to dev environment with `INTENT_DETECTION_CLIENT=rag`
+
+### Phase 2: QA Testing (1 week)
+- 🎯 Run automated test suite
+- 🎯 Manual testing of all flows
+- 🎯 Load testing
+- 🎯 Compare responses with Dialogflow
+
+### Phase 3: Production Pilot (2-3 weeks)
+- 🎯 Deploy with feature flag
+- 🎯 Gradual rollout: 10% → 50% → 100%
+- 🎯 Monitor metrics (response time, errors)
+- 🎯 Keep Dialogflow as fallback
+
+### Phase 4: Full Migration
+- 🎯 Set `INTENT_DETECTION_CLIENT=rag` for all environments
+- 🎯 Monitor for 2 weeks
+- 🎯 Remove Dialogflow dependencies (optional)
+
+---
+
+## 🔍 **Monitoring**
+
+### Key Metrics
+
+| Metric | Target | How to Monitor |
+|--------|--------|----------------|
+| Response Time (p95) | < 2s | Log entries: "RAG query successful" |
+| Error Rate | < 0.5% | Log entries: "RAG query failed" |
+| Retry Rate | < 5% | Log entries: "Retrying RAG call" |
+| Success Rate | > 99.5% | Count successful vs failed requests |
+
+### Log Patterns
+
+**Success:**
+```
+INFO  Initiating RAG query for session: <session-id>
+INFO  RAG query successful for session: <session-id>
+```
+
+**Failure:**
+```
+ERROR RAG server error for session <session-id>: status=500
+ERROR RAG retries exhausted for session <session-id>
+```
+
+---
+
+## 🛡️ **Rollback Plan**
+
+If issues occur:
+
+### Step 1: Switch Configuration (< 1 minute)
+```bash
+export INTENT_DETECTION_CLIENT=dialogflow
+```
+
+### Step 2: Restart Application
+```bash
+kubectl rollout restart deployment/capa-integracion
+```
+
+### Step 3: Verify
+```
+✓ Intent detection configured to use Dialogflow CX client
+```
+
+**No code changes needed. No data loss.**
