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.
ELevate支持哪些操作系统?
Currently, ELevate project supports the following upgrade and migration directions:
* - migration to CentOS Stream 9 is currently in development and will be available later.
** - migration to Oracle Linux 9 is available with the
Oracle Leapp utility and will not be supported by ELevate project.
Note: If you use cPanel, we recommend using the
cPanel ELevate fork.
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。
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.
