# Migrate from Pydantic v1 to Pydantic v2 { #migrate-from-pydantic-v1-to-pydantic-v2 }

If you have an old FastAPI app, you might be using Pydantic version 1.

FastAPI version 0.100.0 had support for either Pydantic v1 or v2. It would use whichever you had installed.

FastAPI version 0.119.0 introduced partial support for Pydantic v1 from inside of Pydantic v2 (as `pydantic.v1`), to facilitate the migration to v2.

# 從 Pydantic v1 遷移到 Pydantic v2 { #migrate-from-pydantic-v1-to-pydantic-v2 }

如果你有一個舊的 FastAPI 應用，可能正在使用 Pydantic 1 版。

FastAPI 0.100.0 同時支援 Pydantic v1 或 v2，會使用你已安裝的那個版本。

FastAPI 0.119.0 透過 Pydantic v2 內的 `pydantic.v1` 提供對 Pydantic v1 的部分支援，以便遷移到 v2。

FastAPI 0.126.0 移除了對 Pydantic v1 的支援，但在一段時間內仍支援 `pydantic.v1`。

/// warning

Pydantic 團隊自 **Python 3.14** 起，已停止在最新的 Python 版本中支援 Pydantic v1。

這也包含 `pydantic.v1`，在 Python 3.14 及以上版本不再支援。

Eski bir FastAPI uygulamanız varsa, Pydantic'in 1. sürümünü kullanıyor olabilirsiniz.

FastAPI 0.100.0 sürümü, Pydantic v1 veya v2 ile çalışmayı destekliyordu. Hangisi kuruluysa onu kullanıyordu.

FastAPI 0.119.0 sürümü, v2'ye geçişi kolaylaştırmak için, Pydantic v2’nin içinden Pydantic v1’e (`pydantic.v1` olarak) kısmi destek ekledi.

Якщо у вас стара програма FastAPI, можливо, ви використовуєте Pydantic версії 1.

FastAPI версії 0.100.0 підтримував як Pydantic v1, так і v2. Використовувалася та версія, яку ви встановили.

FastAPI версії 0.119.0 запровадив часткову підтримку Pydantic v1 всередині Pydantic v2 (як `pydantic.v1`), щоб спростити перехід на v2.
