RHBA-2020:4882 - Bug Fix Advisory

Topic

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

Description

The leapp package provides 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 package provides modules for the Leapp utility. The cockpit-leapp plug-in enables you to assess upgradability of your system in the web console before performing an in-place upgrade from RHEL 7 to RHEL 8.

The leapp package has been upgraded to version 0.11.1, the leapp-repository package to version 0.12.0, and the cockpit-leapp package to version 0.1.5.

With the general availability of RHEL 8.3, the supported in-place upgrade path is unchanged:

• From RHEL 7.9 to RHEL 8.2 on the 64-bit Intel, IBM POWER 8 (little endian),

and IBM Z architectures

• From RHEL 7.6 to RHEL 8.2 on architectures that require kernel version 4.14:

64-bit ARM, IBM POWER 9 (little endian), and IBM Z (Structure A)

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

IMPORTANT:
To ensure your system remains supported, either update to the latest RHEL 8.3 version or enable the RHEL 8.2 Extended Update Support (EUS) repositories.

Notable enhancements include:

• Leapp now supports user input by generating true/false questions to determine how to proceed with the upgrade.
• You can now upgrade multiple hosts simultaneously using the Satellite web UI.
• The in-place upgrade is now supported for on-demand instances on AWS and Microsoft Azure, using Red Hat Update Infrastructure (RHUI).

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