# AlmaLinux Migration Projects

AlmaLinux offers two projects for migrating your machine, each designed for specific migration paths.

See the general overviews of options to select the tool/project that best fits your requirements.

# AlmaLinux Migration Tool

AlmaLinux Migration Tool (opens new window) can be used to convert your EL8 or EL9 machine to the corresponding version.

The tool supports the following migration paths:

See the Migration Guide for the conversion steps.

# AlmaLinux ELevate Project

The ELevate project is an initiative to support migrations between major versions of RHEL-derivatives.

The Leapp utility (opens new window) and a few patches (opens new window) are used to perform in-place migrations between CentOS 7 and Enterprise Linux (EL) 8, and between EL8 and EL9 systems.

The Red Hat Upgrade Tool (opens new window) is used to perform in-place migration between CentOS 6 and CentOS 7.

TIP

Please note, the ELevate project is designed to perform one-step upgrades. If you wish to perform an upgrade from CentOS7, you need to split the process. Please check the ELevating CentOS7 to AlmaLinux 9 guide for more information.

The ELevate project supports a number of 3rd party repositories:

  • EPEL support is currently available for upgrades to AlmaLinux OS only.
  • Docker CE - for all supported operating systems.
  • MariaDB - for all supported operating systems.
  • Microsoft Linux Package Repositories - for all supported operating systems.
  • nginx - for all supported operating systems.
  • PostgreSQL - for all supported operating systems.
  • Imunify - for upgrades to EL 8.
  • KernelCare - for all supported operating systems.

TIP

You can contribute to the project and add more 3rd party repositories support. See more on the Contribute page.

Currently, the following upgrade paths are available:
