This is a clone of issue OCPBUGS-55985. The following is the description of the original issue:
—
Description of problem:
When .spec.authoritativeAPI: MachineAPI and spec.template.spec.authoritativeAPI: ClusterAPI , the CAPI-authoritative Machine cannot be scale down
Version-Release number of selected component (if applicable):
4.19.0-0.nightly-2025-05-08-151714
How reproducible:
always
Steps to Reproduce:
1.At the very beginning, there is a MachineSet which .spec.authoritativeAPI: MachineAPI and
spec.template.spec.authoritativeAPI: MachineAPI , its replicas: 1 and there is a MAPI-authoritative Machine.

2.Update the MachineSet to .spec.authoritativeAPI: MachineAPI and spec.template.spec.authoritativeAPI: ClusterAPI , update successfully

3.Scale up the MachineSet, a new machine created, it's CAPI-authoritative Machine. The MachineSet replicas: 2 , it contains 1 MAPI-authoritative Machine and 1 CAPI-authoritative Machine.
