大版本升级
It wasn't possible--until now. Move from CentOS 7.x to 8.x version of the RHEL derivative of your choice, or upgrade from 8.x to 9.x within the same derivative. Preserve your applications, your data, and your sanity. 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.
全社区项目
EL易升是以一种与发行版无关的方式开发的，它是作为整个生态系统的工具而构建的，而不仅仅是 AlmaLinux。 EL易升支持迁移到/出其他发行版，并且对所有人开放以做出贡献和增强。
FAQ
什么是ELevate？
ELevate is a project aimed to provide the ability to upgrade between major versions of RHEL-based distributions from 7.x to 8.x and from 8.x to 9.x. It combines Red Hat's Leapp framework with a community-created migration metadata library and service.
这看起来很棒。我怎么才能做贡献？
First join us in the
~migration Mattermost
channel. You can find the tool code
in the AlmaLinux GitHub organization
and you can add/edit/interact with package metadata at https://pes.almalinux.org.
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.

迁移是就地迁移吗？
是的。你所有的数据，应用和设置都将会被保留。
迁移时需不需要重启？
迁移将要求你的系统重启两次。
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.
