Chapter 1. Supported conversion paths

Important

Red Hat recommends that you seek the support of Red Hat Consulting services to ensure that the conversion process is smooth.

The automated conversion process is performed on a running system. The Convert2RHEL utility replaces all RPM packages from the original Linux distribution by their RHEL version. At the end of the process, it is necessary to restart the system to boot the RHEL kernel.

Packages that are available only in the original distribution and do not have corresponding counterparts in RHEL repositories, and third-party packages, which originate neither from the original Linux distribution nor from RHEL, are not affected by the conversion. Red Hat does not provide support for third-party packages that are left unchanged during the conversion process. See the Red Hat policy on supporting third-party software.

Note

The Convert2RHEL utility does not directly affect local users and their data in the /home and /srv directories. However, Convert2RHEL cannot control actions that RPM package scriptlets perform during the conversion process.

Currently, it is possible to convert your systems from the following Linux distributions, architectures, and versions to the corresponding minor version of RHEL listed in Table 1.1.

Because the last available minor version of CentOS Linux is CentOS Linux 8.5, it is not possible to convert from CentOS Linux 8 to the latest available minor version of RHEL 8, which is currently RHEL 8.7.

In addition to the above supported conversion paths, it is also possible to perform an unsupported conversion from CentOS Linux 6 and Oracle Linux 6 to RHEL 6 and from Rocky Linux, Alma Linux, and Scientific Linux to RHEL. For information on unsupported conversions, see How to perform an unsupported conversion from a RHEL-derived Linux distribution to RHEL.

Important

Conversions from CentOS Stream to RHEL are not currently possible.

For information on Red Hat’s support policy for Linux distribution conversions, see Convert2RHEL Support Policy.

Note

If you are converting to RHEL 8.4 or RHEL 8.5, it is recommended to update your system to RHEL 8.7 after the conversion.
