i was migrating my 2 DCs from windows server 2008 R2 to windows server 2016 , and after i have promoted the first server windows server 2016 domain controller .
when i run repadmin /showrepl it gave me an error "The replication operation failed because of a schema mismatch between the servers involved 8418"0x20e2" .
i have tried to follow this article "https://support.microsoft.com/en-us/help/2734946/troubleshooting-ad-replication-error-8418-the-replication-operation-fa" but it did not help , so is there any suggestions ?
