I am moving servers, and with that, going and updating all of the domains A records from the old IP addresses to the new ones. With around 100 domains this is a tedious process.
If I set a DNS record on the primary domain, eg server1.mydomain.com with IP address 1 of new server and server2.mydomian.com of the second new server, then CNAMED every domain to one of those, is that bad ?
This means if I move from this host, I can update one record and all sites will move over ?
Thanks
