Will transferring my domain name from one host to another affect my exchange server?
Posted on 2006-04-25
I currently have a domain registered and hosted with earthlink.com. I have an exchange server that uses this domain name exampledomainname.com. Earthlink is charging me $99.99 per month to host this domain. They say to charge me the new hosting price of $19.99 per month they will have to move my domain/site from their old server to the new one. Then they would have to change the DNS entries on the domain to reflect this move and this could cause an outage for 24 - 72 hours.
My question is, will this affect my exchange email services? It seems as if it would just use the old DNS and MX record settings until the very second the domain switched from one dns server to another and that the new one would just take over with no down time. I can't afford any downtime but I also don't like that they are charging us $100 a month because the plan we signed up for several years ago was at this price point.
I am new to Exchange so if I'm stating this wrong feel free to correct me. The way it seems to me is that my registrar, Earthlink, has my current MX records, A records and DNS settings and why would those change just because they are moving me from an old to a newer server?
