High Availability - If you are using the High Availability add-on, follow the Recommended Practices for Applying Software Updates to a RHEL High Availability or Resilient Storage Cluster Knowledgebase article.As a result, file systems have the same limitations as when they were originally created. Consider especially the following:įile systems formats are intact. Security - You should evaluate this aspect before the upgrade and take additional steps when the upgrade process completes. Note that Red Hat does not support custom actors. For more information, see Handling the migration of your custom and third-party applications. However, in certain cases, you have to create custom actors, which specify actions to be performed by Leapp during the upgrade, for example, reconfiguring an application or installing a specific hardware driver. Applications - You can migrate applications installed on your system by using Leapp.See Preparing a RHEL 7 system for the upgrade for more information. You have access to up-to-date RHEL 7.9 and the target operating system (OS) version (for example, RHEL 8.6) content. Minimum hardware requirements for RHEL 8 are met. See Supported in-place upgrade paths for Red Hat Enterprise Linux for more information. Later releases to the in-place upgrade, including new upgrade paths, features, and bug fixes, will not include these architectures. The final upgrade path for these architectures is from RHEL 7.6 to RHEL 8.4. The IBM POWER 9 (little endian) and 64-bit IBM Z (Structure A) architectures have reached end of life. However, most migrations also involve upgrades, and sometimes the terms are used interchangeably. Moving a user from one laptop to another or a company from one server to another is a migration. Moving from Windows to Linux is a migration. Typically, a migration indicates a change of platform: software or hardware. Typically, you first back up your data according to instructions from Red Hat. A clean install is ideal if you do not need any of the previous data or applications on your systems or if you are developing a new project that does not rely on prior builds.Ī conversion is when you convert your operating system from a different Linux distribution to Red Hat Enterprise Linux. Clean install: A clean install removes all traces of the previously installed operating system, system data, configurations, and applications and installs the latest version of the operating system.The installed applications and utilities, along with the configurations and preferences, are incorporated into the new version.

In-place upgrade: During an in-place upgrade, you replace the earlier version with the new version without removing the earlier version first.
