I know how DNS works and how hosting works, this is more a question about how DreamHost handles 'DNS only' for an existing domain.
I have a domain that is fully hosted on dreamhost. I have a bunch of subdomains, mailboxes and mail forwarders active.
However, now I want to take only the main web hosting (for domain.com and www.domain.com) outside dreamhost.
If I change the domain from 'Fully hosted' to 'DNS only' will I preserve everything (subdomains, mail addresses) and be able to edit the 'A' records for '@' and 'www'?
