RHBA-2024:4214 - Bug Fix Advisory

Topic

An update for leapp and leapp-repository is now available for Red Hat Enterprise Linux 7 Extras.

Description

The leapp packages provide the Leapp utility, a framework for performing an in-place upgrade from Red Hat Enterprise Linux 7 to Red Hat Enterprise Linux 8. The leapp-repository packages provide modules for the Leapp utility.

The possible in-place upgrade paths currently are:

• From RHEL 7.9 to RHEL 8.8 and RHEL 8.10 on the 64-bit Intel, IBM POWER 8 (little endian), and IBM Z architectures.
• From RHEL 7.9 to RHEL 8.8 and RHEL 8.10 on systems with SAP HANA. To ensure your system with SAP HANA remains supported after upgrading to RHEL 8, enable the RHEL 8.8 (or 8.10) Update Services for SAP Solutions (E4S) repositories.

See Supported in-place upgrade paths for Red Hat Enterprise Linux linked from the References section.

For detailed instructions on performing an in-place upgrade, see Upgrading from RHEL 7 to RHEL 8 linked from the References section.
