To Reproduce Steps to reproduce the behavior:

• Customer successfully used /usr/share/openstack-tripleo-heat-templates/tools/baremetal_transition.py tool and subsequent "openstack overcloud node provision" command to move two compute nodes to RHEL 9 role
• When moving third compute node, the process got blocked with the following error:

Before migrating nodes to this role customer did a compute scale-out where TripleO failed to add a node with the same node name to overcloud. We thought that this may be related, so we tuned its record with "provisioned: false", so next index will be used. Unfortunately this didn't help and same error was reported for next index as well.

Expected behavior
Node reprovisioning doesn't throw errors

Bug impact
Upgrade is blocked

Known workaround
None
