Answers to Frequent Questions
ELevate is a project aimed to provide the ability to upgrade between major versions of RHEL-based distributions. First announced by AlmaLinux in 2021, ELevate combines two key components: updates to the open source LEAPP project and a data library called leapp-data. These together allow users to upgrade in-place from an unsupported operating system to a modern operating system, and then from 8 to 9 of that operating system.
Individuals and organizations that require an enterprise-grade linux distribution, without the need for a commercial license agreement. AlmaLinux OS is also a perfect replacement for anyone who has historically relied on the CentOS Linux releases to achieve computing objectives, and for whom CentOS Stream is not the right solution.
ELevate has been used to migrate production environments across industries and across the world, but we still advise caution. 根据应用和配置的不同，每个环境都是不同的、独特的。
To avoid any surprises, we highly recommend that you test upgrades scenarios in a virtual machine or sandbox before running a upgrades in production.
Yes, and yes! All your data, applications and settings will be kept. Migrations will require your system to reboot twice.
