Migrating to the latest version ofRed Hat® Enterprise Linux®—whether upgrading your existingsubscription or migrating from a completely differentLinux distro or operating system (OS)—is supported by 3 different Red Hat solutions:

• A software tool that upgrades existing Red Hat Enterprise Linux subscriptions
• A software tool that migrates CentOS or Oracle Linux distributions
• A hands-on program to help you migrate from a non-Linux OS, like Unix or other non-Linux systems.

These migration tools and programsautomate many inventory and remediation steps associated with upgrading your subscription or migrating from another Linux distro. While our consultants and services teams have teamed up with certified partners to operationalize migrations from non-Linux OSs.

• Not ready to upgrade your Red Hat Enterprise Linux 7 subscription? Take advantage of Extended Lifecycle Support (ELS) for up to 4 additional years of maintenance support until May 31, 2029.
• Use the Leapp command line utility in Red Hat Enterprise Linux 7 to upgrade to Red Hat Enterprise Linux 8.
• Use the Convert2RHEL command line utility in CentOS Linux and Oracle Linux to migrate to Red Hat Enterprise Linux 8
• Request a discovery session to refactor from a non-Linux distribution to Red Hat Enterprise Linux.

Red Hat Enterprise Linux 7reached end of maintenance on June 30, 2024.Upgrade now toRed Hat Enterprise Linux 8 totake full advantage of all the latestsecurity, automation, performance,cloud, andedge capabilities.

We developed theLeapp command line utility to help reduce therisk associated with upgrading from Red Hat Enterprise Linux 7 to 8—and to reduce a system administrator’s scope of work at the beginning and end of theupgrade process. It helps reduce human errors and makes OS version control less stressful than yesterday’s major OS upgrades.

Leapp keeps sys admins from checking every workload,configuration, and application for compatibility issues, because it automatically highlights potential incompatibilities. Leapp even suggests how to fix them—like how an app should be reconfigured or which hardware driver to install. The actual upgrade is performed in-place with limited downtime or latency. Configuration, customization, and preferences are preserved.

Staying true to ouropen source ethos, Leapp is a self-service utility. You can download and run it by yourself. But our team ofRed Hat consultants is also available to help you prepare for, run, and check your migration. Or—if you’re upgrading from Red Hat Enterprise Linux 6 or earlier—follow these steps to prepare your OS for the Leapp utility.

We built the downloadableConvert2RHEL command line utility to help you migrate fromCentOS Linux or Oracle Linux to Red Hat Enterprise Linux. The utility automatically identifies and replaces RPM packages from your original Linux distribution (like theLinux kernel) with Red Hat Enterprise Linux equivalents. Even Salesforce is converting their complete infrastructure from CentOS Linux to Red Hat Enterprise Linux.

Once you have rebooted the system into the Red Hat Enterprise Linux environment, you can build a list of unchanged custom or third-party packages (those without a Red Hat Enterprise Linux equivalent) and validate them on the newly converted system.

As with the other migration utility, you can download and run Convert2RHEL by yourself or with help from Red Hat Consulting.

Consider using theCentOS Linux migration assessment for a more comprehensive understanding and personalized guidance on your migration path.

Migrating from a non-Linux system (like from Unix to Linux) or from a legacy version of Red Hat Enterprise Linux (version 6 or earlier) is anexercise in investigation. Red Hat Consulting, Red Hat Partners, and Red Hat Training and Certification form the foundation of our OS refactoring program that’s based in investigation and problem solving.

• Red Hat Consulting will help compile lists of existing packages, modules, and applications, as well as any third-party or custom software. We’ll look for anything written in formal languages (likeJava), shell scripts (like bash), or scripting languages (like Python), and determine what Red Hat Enterprise Linux natively supports and what workloads need to be modified.
• Red Hat Partners bring certified hardware, software, clouds, and services to your migration—helping you update any legacy hardware tied to Unix systems and create a more flexible, modernhybrid cloud infrastructure. This provides system architects with thousands of certified hardware and software solutions for Red Hat Enterprise Linux— includingSAP,Microsoft SQL, and many IBM products.
• Red Hat Training and Certification provides tutorials on how to take full advantage of theLinux command line and Kernel processes. We can help system administrators and developers understand the power associated with full source code access, and how to contribute to upstream open source communities.
