Если у вас старое приложение FastAPI с Pydantic v1, здесь я покажу, как мигрировать на Pydantic v2, и **новые возможности в FastAPI 0.119.0**, которые помогут выполнить постепенную миграцию.

## Официальное руководство { #official-guide }

У Pydantic есть официальное <a href="https://docs.pydantic.dev/latest/migration/" class="external-link" target="_blank">руководство по миграции</a> с v1 на v2.
