    Hello @fegume xx ,

    Thank you for posting here.

    After my resaerch, the Ldap atrributes UNIX can be migrated, too.

    For more information, we can refer to the following two similar cases.

    Why an attribute cannot be removed from the Active directory Schema

    By the way, the minimum requirement to add a Windows Server 2019 Domain Controller is a Windows Server 2008 functional level. The domain also has to use DFS-R as the engine to replicate SYSVOL.

    Hope the information above is helpful.

    Should you have any question or concern, please feel free to let us know.

    Tip: you had better test in your lab for the migration above if possible.

    Best Regards,
    Daisy Zhou
