I want to change my web site domain name but still want to use the same IP address of the website. I want to make the change that both old name and new name are accessible for 6 months. After 6 months, the web page is only accessible to the new name. The old name holds an A record.What process can I use to change the name of the server on the domain's DNS without any gap? And suggest the timeline for this change to make it a seamless transition
2 domain names with 1 IP address in a server
