Applying the FFU procedure [1], an environment with CEPH Storage nodes based on both the overcloud-minimal image and RHEL 8.10 has been upgraded from RHOSP 16.2 to 17.

As unexpected effect, the openstack leap upgrade of the CEPH Storage nodes failed on these conflicts:

~~~
file /etc/leapp/files/device_driver_deprecation_data.json conflicts between attempted installs of leapp-repository-openstack-0.0.13-1.el8ost.noarch and leapp-upgrade-el8toel9-0.21.0-2.el8_10.noarch
file /etc/leapp/files/pes-events.json conflicts between attempted installs of leapp-repository-openstack-0.0.13-1.el8ost.noarch and leapp-upgrade-el8toel9-0.21.0-2.el8_10.noarch
file /etc/leapp/files/repomap.json conflicts between attempted installs of leapp-repository-openstack-0.0.13-1.el8ost.noarch and leapp-upgrade-el8toel9-0.21.0-2.el8_10.noarch

To bypass this issue and upgrade the CEPH Storage nodes to RHEL 9.2, the following steps were performed in the node to up upgraded:

• If it was configured, delete the versionlock, yum versionlock clear, in the CEPH Storage node (see OSPRH-13485)
• Disable repos non EUS in the CEPH Storage node
• Enable EUS repos in the CEPH Storage node
• "yum distro-sync subscription-manager*" in the CPEH Storage node (see https://access.redhat.com/solutions/7085985)
• run the openstack leap upgrade process for the CPEH Storage node
