A small question about redirection (forwarding) and aliases (CNAME records type).
If you want to migrate to certain areas on another DNS infrastructure but without losing the old links, you can allow forwards between new and old DNS servers. This way, if the new server does not support the requested domain, it returns the query on the old server using the forward and it is he who knows the answer.
Is it what the alias but then what's the point? Can they be used to migrate the DNS service?
