We have AD structure as below
PDC : (hostname1).abc.com
BDC: (hostname2).abc.com
Child domain: (hostname).d.abc.com
Child PDC : (hostname).e.d.abc.com
Child BDC : (hostname).e.d.abc.com
We have migrated
PDC : (hostname1).abc.com
BDC: (hostname2).abc.com
and after migration
PDC : (hostname3).abc.com
BDC: (hostname1).abc.com
demore: (hostname1).abc.com
and it is done successfully
Now we are going to migrate
Child PDC : (hostname1).e.d.abc.com operating system: win server 2008 r2
Child BDC : (hostname2).e.d.abc.com operatin system : winserver 2003
to
Child PDC : (hostname3).e.d.abc.com operatin system : winserver 2012
Child BDC : (hostname1).e.d.abc.com operating system: win server 2008 r2
But we got error during migration of child domain from win server 2008 r2 to win server 2012
"DNS cannot be installed on this domain controller because this domain does not host DNS"
