### 3. Log Aggregation Setup
- Configure centralized logging
- Set up log shipping
- Handle high volume
- Implement failover

### 4. Correlation ID Injection
- Implement trace IDs
- Propagate across services
- Handle async operations
- Enable distributed tracing

### 5. Log Level Normalization
- Standardize log levels
- Map between frameworks
- Configure filtering
- Handle verbosity

### 6. Retention Policy Migration
- Define retention rules
- Implement rotation
- Handle archival
- Manage storage
