Convert2RHEL is a command line utility that analyzes your system’s readiness and converts RPM-based Linux operating systems (OS) to Red Hat Enterprise Linux. It’s an automated way to standardize on Red Hat Enterprise Linux instead of manually redeploying all your workloads.
Convert2RHEL minimizes the need for costly redeployment projects and reduces administrative burden by maintaining existing OS customizations, configurations, and preferences during the conversion.
The CentOS Project will discontinue updates and releases of CentOS Linux® 7 on June 30, 2024. This means current CentOS Linux users will need to choose a migration path to continue receiving security patches and updates.
Identify a conversion path
Supported conversion paths include:
- CentOS Linux 7 to Red Hat Enterprise Linux 7
- CentOS Linux 8 to Red Hat Enterprise Linux 8
- Oracle Linux 7 to Red Hat Enterprise Linux 7
- Oracle Linux 8 to Red Hat Enterprise Linux 8
- Alma Linux 8 to Red Hat Enterprise Linux 8
- Rocky Linux 8 to Red Hat Enterprise Linux 8
Conversions from CentOS Linux 6 and Oracle Linux 6 to Red Hat Enterprise Linux are unsupported—since Red Hat Enterprise Linux 6 is outside the lifecycle maintenance phase—but guidance is provided in this documentation.
Prepare to convert
Read this documentation for guidance, additional features, and information on known limitations. Verify that your system is supported for conversion to Red Hat Enterprise Linux, and then back it up. Use the documentation—which includes step-by-step instructions on how to assess system applications and data—to identify potential complications with workloads, configurations, or applications, and proactively remediate issues. Identify compatibility issues and layered applications prior to your migration in order to minimize risk and optimize the system.
If challenges or complexities arise during this phase, reach out to Red Hat Consulting. These experts can help convert more complex applications and workloads, as well as help standardize processes, analyze workloads, and automate migration variants, all of which can help minimize risks associated with OS conversion.
Review the pre-conversion analysis report
To assess whether your systems can be converted to Red Hat Enterprise Linux, run the pre-conversion analysis. This generates a report that summarizes potential problems and suggests recommended solutions. The report also helps you decide whether it is possible or advisable to proceed with the conversion to Red Hat Enterprise Linux.
After backing up your existing OS, run the convert2RHEL utility while following along with the documentation. Convert2RHEL will automatically identify and replace OS packages from your original Linux distribution with Red Hat Enterprise Linux equivalents, and convert2RHEL is officially supported to help troubleshoot conversion variants.
Once the conversion is successful, reboot the system into Red Hat Enterprise Linux. It may be necessary to reinstall third-party RPMs or reconfigure system services after conversion.
If your system is running Red Hat Enterprise Linux 7 after convert2RHEL has finished, take a moment to assess your support situation. If you took advantage of our Red Hat Enterprise Linux for Third Party Linux Migration offer or purchased an Extended Life Cycle (ELS) add-on subscription, then you have additional time to upgrade to a newer version. If you do not have either of these extended support options, we recommend upgrading to a newer, supported version of Red Hat Enterprise Linux before version 7 reaches end of maintenance on June 30, 2024.
Get back to work
Once the conversion and upgrade are complete, you have access to all the latest Red Hat Enterprise Linux updates—as well as all the performance, support, management, and security capabilities that Red Hat Enterprise Linux includes.
