RHBA-2020:1959 - 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 leapp and leapp-repository packages have been upgraded to version 0.10.0, which provides a number of bug fixes and enhancements over the previous versions. (BZ#1821712, BZ#1821710)

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

The supported in-place upgrade path is:

• From RHEL 7.8 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.

Notable enhancements include:

• You can now use additional custom repositories for an in-place upgrade from RHEL 7 to RHEL 8. It is also possible to upgrade without Red Hat Subscription Manager.
• You can create your own actors to migrate your custom or third-party applications using the Leapp utility.

See Customizing your Red Hat Enterprise Linux in-place upgrade for details.
