大版本升级
截至目前，这并不可能。正如从 CentOS 7.x 迁移到您选择的 RHEL 衍生版本的 8.x 版本，或者在同一衍生版本中从 8.x 升级到 9.x。 维持您的应用程序、数据和精神状态。 运行您需要的最新版本的操作系统和软件。 Run the most recent version of the OS and software you need.
包演化服务
The beating heart of ELevate is the 包演化服务 (PES) which allows you to download, customize and even submit new data sets for packages. Users and maintainers can both utilize the PES to help make migrations smooth and easy.

这是否可以用于生产环境？
ELevate has been used to migrate production environments across industries and across the world, but we still advise caution. Every environment is different and unique based on applications and configurations.
To avoid any surprises, we highly recommend that you test upgrades scenarios in a virtual machine or sandbox before running a upgrades in production.

What does the Package Evolution Service (PES) do?
The Package Evolution Service stores package migration metadata. Metadata answers questions about how packages evolve between major distribution releases. PES supports several classes of rules for packages such as added, removed, renamed, split, merged, and so on. The service also allows everyone to improve the data by adding new actions or even create a custom dataset for packages from third-party or private repositories.
Red Hat提供了一个非免费授权的数据集。你们使用相同的数据集吗？
No. We respect Red Hat’s work and our initial data set was provided by the AlmaLinux OS Foundation with contributions from Oracle.
您的元数据在哪种许可下？
元数据是在 Apache 许可下提供的。
为什么你们支持迁移到其他发行版？
Our contributors have been part of the RHEL ecosystem for a very long time, and we recognized that the CentOS ecosystem is a very large and diverse community. We've developed this project in good faith in the hope that everyone in the community can use and contribute to, no matter which distro you prefer. That's the open source way.
