    Hi @Lucas Budas

    Before promote new domain controller running on Windows 2019 or Windows 2022 , the domain functional level must be Windows 2008 R2 at least and the system replication for sysvol folder is DFS-R.

    Before promote or demote a domain controller , you should may some health check about replication and active directory. Below some commands should help you to identify replication and AD error:

    repadmin /showrepl
