# Migrating from NServiceBus

Migrate from NServiceBus to Svrnty.CQRS.

## Key Differences

| NServiceBus | Svrnty.CQRS |
|-------------|-------------|
| `IHandleMessages<T>` | `ICommandHandler<T>` or `IQueryHandler<T>` |
| Separate message broker | Built-in event streaming |
| Saga pattern | ISaga interface |
| Publish/Subscribe | Event streaming |

## Migration Steps

1. Map message handlers to command/query handlers
2. Convert sagas to ISaga implementations
3. Replace message bus with event streams
4. Update configuration
