Using the Zone File Editor in the DNS Manager, you can copy zone file records from one domain name to another. You can select single or multiple records to copy, and then you can add them to one or multiple domain names.
NOTE: By allowing duplicates, you can keep multiple MX, TXT, and SRV records for your domain name. If you don't allow duplicates, the records you're copying will replace any existing MX, TXT, or SRV records.
