+# Von Pydantic v1 zu Pydantic v2 migrieren { #migrate-from-pydantic-v1-to-pydantic-v2 }
+
+Wenn Sie eine ältere FastAPI-App haben, nutzen Sie möglicherweise Pydantic Version 1.
+
+FastAPI unterstützt seit Version 0.100.0 sowohl Pydantic v1 als auch v2.
+
+Wenn Sie Pydantic v2 installiert hatten, wurde dieses verwendet. Wenn stattdessen Pydantic v1 installiert war, wurde jenes verwendet.
+
+Pydantic v1 ist jetzt deprecatet und die Unterstützung dafür wird in den nächsten Versionen von FastAPI entfernt, Sie sollten also zu **Pydantic v2 migrieren**. Auf diese Weise erhalten Sie die neuesten Features, Verbesserungen und Fixes.
+
+/// warning | Achtung
+
+Außerdem hat das Pydantic-Team die Unterstützung für Pydantic v1 in den neuesten Python-Versionen eingestellt, beginnend mit **Python 3.14**.
+
+Wenn Sie die neuesten Features von Python nutzen möchten, müssen Sie sicherstellen, dass Sie Pydantic v2 verwenden.
+
+///
+
+Wenn Sie eine ältere FastAPI-App mit Pydantic v1 haben, zeige ich Ihnen hier, wie Sie sie zu Pydantic v2 migrieren, und die **neuen Features in FastAPI 0.119.0**, die Ihnen bei einer schrittweisen Migration helfen.
+
+## Offizieller Leitfaden { #official-guide }
+
+Pydantic hat einen offiziellen <a href="https://docs.pydantic.dev/latest/migration/" class="external-link" target="_blank">Migrationsleitfaden</a> von v1 zu v2.
+
+Er enthält auch, was sich geändert hat, wie Validierungen nun korrekter und strikter sind, mögliche Stolpersteine, usw.
+
+Sie können ihn lesen, um besser zu verstehen, was sich geändert hat.
+
+## Tests { #tests }
+
+Stellen Sie sicher, dass Sie [Tests](../tutorial/testing.md){.internal-link target=_blank} für Ihre App haben und diese in Continuous Integration (CI) ausführen.
+
+Auf diese Weise können Sie das Update durchführen und sicherstellen, dass weiterhin alles wie erwartet funktioniert.
+
+## `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 <a href="https://github.com/pydantic/bump-pydantic" class="external-link" target="_blank">`bump-pydantic`</a> vom selben Pydantic-Team verwenden.
+
+Dieses Tool hilft Ihnen, den Großteil des zu ändernden Codes automatisch anzupassen.
+
+Danach können Sie die Tests ausführen und prüfen, ob alles funktioniert. Falls ja, sind Sie fertig. 😎
+
+## Pydantic v1 in v2 { #pydantic-v1-in-v2 }
+
+Pydantic v2 enthält alles aus Pydantic v1 als Untermodul `pydantic.v1`.
+
+Das bedeutet, Sie können die neueste Version von Pydantic v2 installieren und die alten Pydantic‑v1‑Komponenten aus diesem Untermodul importieren und verwenden, als hätten Sie das alte Pydantic v1 installiert.
+
+{* ../../docs_src/pydantic_v1_in_v2/tutorial001_an_py310.py hl[1,4] *}
+
+### FastAPI-Unterstützung für Pydantic v1 in v2 { #fastapi-support-for-pydantic-v1-in-v2 }
+
+Seit FastAPI 0.119.0 gibt es außerdem eine teilweise Unterstützung für Pydantic v1 innerhalb von Pydantic v2, um die Migration auf v2 zu erleichtern.
+
+Sie könnten also Pydantic auf die neueste Version 2 aktualisieren und die Importe so ändern, dass das Untermodul `pydantic.v1` verwendet wird, und in vielen Fällen würde es einfach funktionieren.
+
+{* ../../docs_src/pydantic_v1_in_v2/tutorial002_an_py310.py hl[2,5,15] *}
+
+/// warning | Achtung
+
+Beachten Sie, dass, da das Pydantic‑Team Pydantic v1 in neueren Python‑Versionen nicht mehr unterstützt, beginnend mit Python 3.14, auch die Verwendung von `pydantic.v1` unter Python 3.14 und höher nicht unterstützt wird.
+
+///
+
+### Pydantic v1 und v2 in derselben App { #pydantic-v1-and-v2-on-the-same-app }
+
+Es wird von Pydantic **nicht unterstützt**, dass ein Pydantic‑v2‑Modell Felder hat, die als Pydantic‑v1‑Modelle definiert sind, und umgekehrt.
+
+```mermaid
+graph TB
+    subgraph "❌ Nicht unterstützt"
+        direction TB
+        subgraph V2["Pydantic-v2-Modell"]
+            V1Field["Pydantic-v1-Modell"]
+        end
+        subgraph V1["Pydantic-v1-Modell"]
+            V2Field["Pydantic-v2-Modell"]
+        end
+    end
+
+    style V2 fill:#f9fff3
+    style V1 fill:#fff6f0
+    style V1Field fill:#fff6f0
+    style V2Field fill:#f9fff3
+```
+
+... aber Sie können getrennte Modelle, die Pydantic v1 bzw. v2 nutzen, in derselben App verwenden.
+
+```mermaid
+graph TB
+    subgraph "✅ Unterstützt"
+        direction TB
+        subgraph V2["Pydantic-v2-Modell"]
+            V2Field["Pydantic-v2-Modell"]
+        end
+        subgraph V1["Pydantic-v1-Modell"]
+            V1Field["Pydantic-v1-Modell"]
+        end
+    end
+
+    style V2 fill:#f9fff3
+    style V1 fill:#fff6f0
+    style V1Field fill:#fff6f0
+    style V2Field fill:#f9fff3
+```
+
+In einigen Fällen ist es sogar möglich, sowohl Pydantic‑v1‑ als auch Pydantic‑v2‑Modelle in derselben **Pfadoperation** Ihrer FastAPI‑App zu verwenden:
+
+{* ../../docs_src/pydantic_v1_in_v2/tutorial003_an_py310.py hl[2:3,6,12,21:22] *}
+
+Im obigen Beispiel ist das Eingabemodell ein Pydantic‑v1‑Modell, und das Ausgabemodell (definiert in `response_model=ItemV2`) ist ein Pydantic‑v2‑Modell.
+
+### Pydantic v1 Parameter { #pydantic-v1-parameters }
+
+Wenn Sie einige der FastAPI-spezifischen Tools für Parameter wie `Body`, `Query`, `Form`, usw. zusammen mit Pydantic‑v1‑Modellen verwenden müssen, können Sie die aus `fastapi.temp_pydantic_v1_params` importieren, während Sie die Migration zu Pydantic v2 abschließen:
+
+{* ../../docs_src/pydantic_v1_in_v2/tutorial004_an_py310.py hl[4,18] *}
+
+### In Schritten migrieren { #migrate-in-steps }
+
+/// tip | Tipp
+
+Probieren Sie zuerst `bump-pydantic` aus. Wenn Ihre Tests erfolgreich sind und das funktioniert, sind Sie mit einem einzigen Befehl fertig. ✨
+
+///
+
+Wenn `bump-pydantic` für Ihren Anwendungsfall nicht funktioniert, können Sie die Unterstützung für Pydantic‑v1‑ und Pydantic‑v2‑Modelle in derselben App nutzen, um die Migration zu Pydantic v2 schrittweise durchzuführen.
+
+Sie könnten zuerst Pydantic auf die neueste Version 2 aktualisieren und die Importe so ändern, dass für all Ihre Modelle `pydantic.v1` verwendet wird.
+
+Anschließend können Sie beginnen, Ihre Modelle gruppenweise von Pydantic v1 auf v2 zu migrieren – in kleinen, schrittweisen Etappen. 🚶

+* 📝 Update note for untranslated pages. PR [#14257](https://github.com/fastapi/fastapi/pull/14257) by [@YuriiMotov](https://github.com/YuriiMotov).
+
+## 0.120.2
+
+### Fixes
+
+* 🐛 Fix separation of schemas with nested models introduced in 0.119.0. PR [#14246](https://github.com/fastapi/fastapi/pull/14246) by [@tiangolo](https://github.com/tiangolo).

+
+## 0.120.1
+
+### Upgrades
+
+* ⬆️ Bump Starlette to <`0.50.0`. PR [#14234](https://github.com/fastapi/fastapi/pull/14234) by [@YuriiMotov](https://github.com/YuriiMotov).

+
+## 0.120.0
+
+There are no major nor breaking changes in this release. ☕️
+
+The internal reference documentation now uses `annotated_doc.Doc` instead of `typing_extensions.Doc`, this adds a new (very small) dependency on [`annotated-doc`](https://github.com/fastapi/annotated-doc), a package made just to provide that `Doc` documentation utility class.
+
+I would expect `typing_extensions.Doc` to be deprecated and then removed at some point from `typing_extensions`, for that reason there's the new `annotated-doc` micro-package. If you are curious about this, you can read more in the repo for [`annotated-doc`](https://github.com/fastapi/annotated-doc).
+
+This new version `0.120.0` only contains that transition to the new home package for that utility class `Doc`.
+
+### Translations
+
+* 🌐 Sync German docs. PR [#14188](https://github.com/fastapi/fastapi/pull/14188) by [@nilslindemann](https://github.com/nilslindemann).
