红帽全球峰会4.5. OpenShift Virtualization 的先决条件
以下先决条件适用于从一个 OpenShift Virtualization 集群迁移到另一个 OpenShift Virtualization 集群：
- 源和目标 OpenShift Virtualization 集群都必须安装相同的 Migration Toolkit for Virtualization (MTV)版本。
- 源集群必须使用 OpenShift Virtualization 4.16 或更高版本。
- 不支持从 OpenShift Virtualization 版本迁移到较早版本。
- 如果当前版本的 MTV 支持，则支持从早期版本的 OpenShift Virtualization 迁移到更新的版本。例如，如果 OpenShift Virtualization 的当前版本是 4.18，则代表从 4.16 或 4.17 迁移到版本 4.18，但从版本 4.15 迁移到任何版本不被支持。
重要
强烈建议仅在具有相同 OpenShift Virtualization 版本的集群之间迁移，但从早期版本的 OpenShift Virtualization 迁移到更新的版本时被支持。
