I have a current server with a variety of websites on it. My name servers are the same has my business domain. This server uses cpanel.
I am going to buy dedicated hosting with a bare bones ubuntu server install, and I need to slowly transfer each site on the old server to the new, with the least possible downtime. How do I assign the new server with nameservers so that when I tranfer a site from the old server to the new, that that site is up and available to the public. I am not sure of the exact process. What is the process or workflow so that there is little to no downtime?
