1.4. Leapp upgrade usage in Red Hat OpenStack Platform
The long-life Red Hat OpenStack Platform upgrade requires a base operating system upgrade from Red Hat Enterprise Linux (RHEL) 8.4 to RHEL 9.2. The upgrade process uses the Leapp utility to perform the upgrade to RHEL 9.2. However, some aspects of the Leapp upgrade are customized to ensure that you are upgrading specifically from RHEL 8.4 to RHEL 9.2. To upgrade your operating system to RHEL 9.2, see Performing the undercloud system upgrade.
Limitations
For information on potential limitations that might affect your upgrade, see the following sections from the Upgrading from RHEL 8 to RHEL 9 guide:
If any known limitations affect your environment, seek advice from the Red Hat Technical Support Team.
Troubleshooting
For information about troubleshooting potential Leapp issues, see Troubleshooting in Upgrading from RHEL 8 to RHEL 9.
