Copy DNS records from Standard Zone to Active Directory Zone

I need to copy all records from one zone to another in Windows 2003 DNS.
Both 
zones are running on the same server. Generally this is straight forward
as 
you can edit the .dns file in %SystemRoot%\system32\dns , but in this case

the target zone is Active Directory Integrated so the file doesn’t
exist. Is 
there a way I can copy the records to the target zone without changing it 
from Active Directory Integrated to Standard Primary? 

Thanks
