关于

大版本升级

It wasn't possible--until now. Move between major versions of RHEL-derivatives: from CentOS 6.x to CentOS 7.x, 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. 运行所需的最新版本操作系统和软件。

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。

What does the Package Evolution Service (PES) do?
软件包演进服务存储软件包迁移元数据。 Metadata answers questions about how packages evolve between major distribution releases. PES 支持几类软件包规则,如添加、删除、重命名、拆分、合并等。 该服务还允许每个人通过添加新操作来改进数据,甚至为来自第三方或私人资源库的软件包创建自定义数据集。
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. 无论你使用哪个发行版,我们本着诚意开发这个项目,希望社区中的每个人都能使用它并为之做出贡献。 这就是开源方式。
