ELevate enables migration between major versions of RHEL® derivatives. Easily go from CentOS 7.x to any 8.x of your choice

About

Major Version Upgrades

It wasn't possible--until now. Easily migrate between major versions of RHEL-based distributions from 7.x to 8.x. Preserve your applications, your data, and your sanity. Run the most recent version of the OS and software you need.

Package Evolution Service

The beating heart of ELevate is the Package Evolution Service (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.

Community-wide Project

ELevate is developed in a distribution agnostic way and is built as a tool for the whole ecosystem, not just AlmaLinux. ELevate supports migrating to/from other distributions and is open for all to contribute to and enhance.

FAQ
What is ELevate?
ELevate is a project aimed to provide the ability to migrate between major versions of RHEL-based distributions from 7.x to 8.x. It combines Red Hat's Leapp framework with a community created library and service for the migration metadata set required for it.
This looks awesome. How can I contribute?
First, join us at #migration Mattermost channel. You can find the tool code here: https://github.com/AlmaLinux/leapp-repository/tree/almalinux and you can add/edit/interact with package metadata at https://pes.almalinux.org.
Is this ready for production?
YMMV. Every environment is different and unique based on applications and configurations. Since this is still under development, to avoid any surprises, we highly recommend that you test migrations scenarios in a VM or sandbox before running a migration in production.
What operating systems does ELevate support?
Currently ELevate provides Leapp data for migration from CentOS 7 to the following OS:
  • AlmaLinux OS 8
  • CentOS Stream 8
  • Oracle Linux 8
  • Rocky Linux 8
Will migration be "in-place?"
Yes. All your data, applications and settings will be kept.
Is this live or does it require a reboot?
Migrations will require your system to reboot twice.
What does the Package Evolution Service 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 offers a data set which is non-freely licensed. Are you using this same data set?
No. We respect Red Hat’s work and our initial data set was provided by the AlmaLinux Foundation and contributions from Oracle.
What license is your metadata under?
The metadata is provided under an Apache License.
Why are you supporting migration to other distributions?
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.
