My employer wants to move a website from its current host to a VM in Microsoft Azure. The domain will remain the same, but the IP of the host machine will be different, obviously. The site requires SSL, starting with the home page.
What is the best way to move this site from one machine to another, with zero (or as close to zreo as possible) downtime? Apparently my boss seems to think that simply changing the DNS information with the registrar to point to the new IP won't work. We are looking at redirects or a service like "DNS Made Easy", but nobody seems to be sure if we need another SSL certificate for the new server, and if getting one will invalidate the old one. Ideas/suggestions?
