Note that CentOS Linux 6 and Oracle Linux 6 conversions use the unsupported Convert2RHEL utility. If you are using an earlier version of CentOS Linux or Oracle Linux, namely versions 6 or 7, you can convert your operating system to RHEL and then perform an in-place upgrade to RHEL 8. For more information, see Converting from an RPM-based Linux distribution to RHEL. If you are using CentOS Linux 8 or Oracle Linux 8, you can convert your operating system to RHEL 8 using the Red Hat-supported Convert2RHEL utility. Major differences between RHEL 8 and RHEL 9 are documented in Considerations in adopting RHEL 9.Ĭonversion from a different Linux distribution to RHEL Instructions on how to perform an in-place upgrade from RHEL 8 to RHEL 9 using the Leapp utility are provided by the document Upgrading from RHEL 8 to RHEL 9. To upgrade from RHEL 6.10 to RHEL 8, follow instructions in Upgrading from RHEL 6 to RHEL 8. To disable data collection, set the LEAPP_NO_RHSM_FACTS environment variable to 1. Red Hat now collects upgrade-related data, such as the upgrade start and end times and whether the upgrade was successful, for utility usage analysis. To disable the automatic registration, set the LEAPP_NO_INSIGHTS_REGISTER environment variable to 1. Systems that are subscribed to RHSM are now automatically registered with Red Hat Insights. To disable the automatic check, use the -nogpgcheck option when performing the upgrade. RPM signatures are now automatically checked during the in-place upgrade. In-place upgrades using an ISO image that contains the target version are now possible. For more information, see Supported in-place upgrade paths for Red Hat Enterprise Linux. The RHEL in-place upgrade path strategy has changed. See New features - The web console for more information. You can also apply the following cryptographic subpolicies through the graphical interface now: DEFAULT:SHA1, LEGACY:AD-SUPPORT, and FIPS:OSPP. The RHEL web console now performs additional steps for binding LUKS-encrypted root volumes to NBDE deployments. For more information about the new rebuilding process, see the README.md file which is available in the SRPM package of the Red Hat build of OpenJDK and is also installed by the java-*-openjdk-headless packages under the /usr/share/doc tree.įor more information, see OpenJDK documentation. Because of this update, there is a change in the process of rebuilding the OpenJDK packages on RHEL from the source RPM. The Red Hat build of OpenJDK packages share a single set of binaries between its portable Linux releases, RHEL 8.8 and later releases. The java-1.8.0-openjdk packages, which provide the OpenJDK 8 Java Runtime Environment and the OpenJDK 8 Java Software Development Kit. The java-11-openjdk packages, which provide the OpenJDK 11 Java Runtime Environment and the OpenJDK 11 Java Software Development Kit. The java-17-openjdk packages, which provide the OpenJDK 17 Java Runtime Environment and the OpenJDK 17 Java Software Development Kit.
