I have a web server that hosts 200+ domains but it needs to be moved to another data center and get a new IP address. But since all DNS settings have to be updated manually, I thought about whether you could set up some kind of transparent proxy at the old IP address that forwards all http/https traffic to the new IP. So visitors do not discover the move to the DNS is being corrected.
My first thought was to use nginx for it, but thinking it will cause problems with SSL certificates on the domains. Is there a good way to solve the problem?
