Active Directory Domain Services could not transfer the remaining data in directory partition DC=DomainDnsZones,DC=[domain],DC=local to
Active Directory Domain Controller \\red.[domain].local.

“The directory service is missing mandatory configuration information, and is unable to determine the ownership of floating single-master operation roles.”

This is becuase a legacy server is still the “fSMORoleOwner” for DomainDnsZones and ForestDnsZones

Download fixfsmo.vbs from below

Run this script on the server which has all the FSMO roles

cscript fixfsmo.vbs DC=DomainDnsZones,DC=[domain],DC=local

cscript fixfsmo.vbs DC=ForestDnsZones,DC=[domain],DC=local
