## 官方指南 { #official-guide }

Pydantic 提供從 v1 遷移到 v2 的官方[遷移指南](https://docs.pydantic.dev/latest/migration/)。

其中包含變更內容、驗證如何更正確且更嚴格、可能的注意事項等。

你可以先閱讀以更好理解具體變更。

## 測試 { #tests }

確保你的應用有[測試](../tutorial/testing.md)，並在 CI（持續整合）上執行。

如此一來，你可以升級後確認一切仍如預期運作。

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

在許多情況下，若你使用的是未自訂的標準 Pydantic 模型，多數遷移步驟都能自動化完成。
