'Change Hostnames and IP Addresses with another host - Does it require a DNS update?
I have a new Linux database server I am working on with a certain hostname and ipaddress. I want to change it's hostname and ipaddress with my old Linux database server's at the time of going live with the new server. I understand this requires only update on the new server's hosts file.
My team says it would need a DNS update. I don't see why it would require a DNS update. Because a DNS is a mapping between hostname and ipaddress and it hasn't changed.
Could anyone clarify?
Thank You, Madhuri Dara
