![]() We will need to install the convert2rhel utility, which is available in the EPEL 6 repository. Once that has been taken care of, we will check the contents of /etc/centos-release to find the specific version of CentOS that is in use: # cat /etc/centos-release CentOS release 6.10 (Final) The first step is to create a full system backup of the system that is being converted in case there are unexpected issues during the conversion that require the system to be restored. Now that the Satellite configuration is in place, we can jump over to the CentOS 6 system that we would like to convert. Do you know about Red Hat Enterprise Linux's latest features and updates?Ĭheck out the What's new in RHEL page today! Converting the System to RHEL For more information, see the documentation here. In this example, the activation key is named RHEL6. Also ensure that the Release Version is set to 6Server, and that the appropriate RHEL subscriptions have been added to the activation key, as the system being converted will require a valid subscription. For more information on how to complete this, see the documentation here.įinally, ensure that an activation key has been created that is configured to use the previously covered content view. In this example, I am using a content view with the name of RHEL6. ![]() Then, verify that these two repositories are part of a content view, and that the content view has been published and promoted as needed. For more information on how to complete this, see the documentation here. If you are using a different version of Satellite, find the corresponding Satellite Tools repository for your version of Satellite. In this example, we are using Satellite 6.6, so the proper repository is rhel-6-server-satellite-tools-6.6-rpms. We first need to ensure that the rhel-6-server-rpms and the appropropriate Satellite Tools repository for RHEL 6 are enabled and synchronized. In many environments this Satellite configuration will already be in place, and it will simply need to be validated. In this post we are completing a RHEL 6 conversion, however the process is similar for RHEL 7 by substituting the appropriate RHEL 7 repositories. The first step to converting our CentOS 6 system to RHEL 6 using Satellite is to ensure the proper resources are configured in the Satellite environment. Optionally, the converted system will be configured for Red Hat Insights, which allows you to proactively identify and remediate a wide variety of potential issues. When utilizing Satellite for the conversion, the packages being reinstalled will be upgraded to the version provided by Satellite (if using RHEL DVD images for the conversion, these packages will likely be out of date and require an upgrade following the conversion). The converted system will be registered to Satellite for future management. For steps to upgrade from RHEL 7 to RHEL 8, see this documentation. For steps to upgrade to RHEL 7, please see this solution article. If you do not wish to purchase ELS, we recommend that you first convert to RHEL 6, and then perform an upgrade to RHEL 7 or RHEL 8. See the Red Hat policy on supporting third-party software for more information. Note that Red Hat support may not be provided for the third-party packages that are left unchanged during the conversion process. The converted system will be a Red Hat Enterprise Linux 6 system, eligible to receive support, including the optional Extended Life-cycle Support (ELS) which provides RHEL 6 support until June, 2024. Some of the benefits that will be realized in the process of converting from CentOS 6 to RHEL 6 following this process include: We will go through an example conversion of a CentOS 6 server to RHEL 6. One option for this is to create a custom repository pointed to a mounted RHEL DVD or ISO image, as covered in this article.Īnother option is to utilize Red Hat Satellite to provide the RHEL repository, which is what this blog post will focus on. Due to this, one of the requirements of convert2rhel is that it has access to a RHEL repository for the target version of RHEL being converted to. The conversion process works by reinstalling each of the source operating system’s packages with RHEL versions of the package. Red Hat recently released the Convert2RHEL utility, which allows CentOS, or Oracle Linux, version 6 or 7 servers on the x86_64 architecture to be converted to Red Hat Enterprise Linux (RHEL): ![]() ![]() Explore Red Hat’s options to help ease your migration, including Red Hat Enterprise Linux 7 for Third Party Linux Migration. On June 30, 2024, CentOS Linux 7 will reach End of Life (EOL). ![]()
