## `bump-pydantic` { #bump-pydantic }

In vielen Fällen, wenn Sie reguläre Pydantic-Modelle ohne Anpassungen verwenden, können Sie den Großteil des Prozesses der Migration von Pydantic v1 auf Pydantic v2 automatisieren.

Sie können [`bump-pydantic`](https://github.com/pydantic/bump-pydantic) vom selben Pydantic-Team verwenden.

In particular, this may be a good alternative to logic in a middleware.

For example, if you want to read or manipulate the request body before it is processed by your application.

/// danger

This is an "advanced" feature.

If you are just starting with **FastAPI** you might want to skip this section.
