### Negative Consequences

* **Historical inconsistencies**: Existing code may contain British English spellings that cannot be changed due to backward compatibility

### Migration and Enforcement

* **New code**: All new contributions must use American English

		// Preserve older credential if we do not have
		// root credentials set via environment variable.

	// Init compression config. For future migration, Compression config needs to be copied over from previous version.

# This script is used to test the migration of IAM content from old minio
# instance to new minio instance.
#
# To run it locally, start the LDAP server in github.com/minio/minio-iam-testing
# repo (e.g. make podman-run), and then run this script.
#
# This script assumes that LDAP server is at:
#
#   `localhost:389`
#
# if this is not the case, set the environment variable
# `_MINIO_LDAP_TEST_SERVER`.

Pydantic v1을 사용하는 오래된 FastAPI 앱이 있다면, 여기서는 이를 Pydantic v2로 마이그레이션하는 방법과 점진적 마이그레이션을 돕는 **FastAPI 0.119.0의 기능**을 소개하겠습니다.

## 공식 가이드 { #official-guide }

Pydantic에는 v1에서 v2로의 공식 [마이그레이션 가이드](https://docs.pydantic.dev/latest/migration/)가 있습니다.

여기에는 무엇이 바뀌었는지, 검증이 이제 어떻게 더 정확하고 엄격해졌는지, 가능한 주의사항 등도 포함되어 있습니다.

변경된 내용을 더 잘 이해하기 위해 읽어보면 좋습니다.

## 테스트 { #tests }

앱에 대한 [테스트](../tutorial/testing.md)가 있는지 확인하고, 지속적 통합(CI)에서 테스트를 실행하세요.

如果你的舊 FastAPI 應用仍使用 Pydantic v1，這裡會示範如何遷移到 Pydantic v2，並介紹 **FastAPI 0.119.0** 中可協助你逐步遷移的功能。

## 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 }

Here we create the tables on an application startup event.

For production you would probably use a migration script that runs before you start your app. 🤓

/// tip

SQLModel will have migration utilities wrapping Alembic, but for now, you can use [Alembic](https://alembic.sqlalchemy.org/en/latest/) directly.

	// If bucket metadata is missing look for legacy files,

### CSI Migration Beta

The Kubernetes in-tree storage plugin to Container Storage Interface (CSI) migration infrastructure is now beta in Kubernetes v1.17. CSI migration was introduced as alpha in Kubernetes v1.14.

## Known Issues
- volumeDevices mapping ignored when container is privileged

No, an upgrade should not cause any downtime. However, on the first startup -
since MinIO will attempt to migrate any existing IAM data - the boot process may
take slightly longer, but may not be visibly noticeable. Once the migration has
