Can you confirm if all remaining Samba4 DCs are fully demoted, or are any still acting as authoritative domain controllers? I can systematically stabilize your hybrid Samba4 → Windows AD environment by analyzing replication metadata, repairing missing or inconsistent security descriptors, cleaning up DNS application partitions, and resolving SYSVOL / replication inconsistencies, then validate FSMO role readiness and prepare the environment for a smooth upgrade to Windows Server 2016, all while keeping your production AD intact — could you clarify if you want me to also handle the pre-upgrade health checks and remediation in a single engagement or just the immediate cleanup first?
