  • Hi Joe,

    You can install a new domain controller with Windows Server 2019, but ensure that you have at least 2012 R2 as Domain & Forest functional level, more details about this:

          Forest and Domain Functional Levels

    If you want to check the functional level, following the Powershell commands:

    • Domain functional: Get-ADDomain | fl Name,DomainMode
    • Forest functional: Get-ADForest | fl Name,ForestMode
