Hello One of my clients would like to use a new domain name for an existing website. The old name is to be kept as an alias and the content on the page and a subdomain are to be retained. The previous site uses a Letsencrypt certificate, which should also be retained. The new site should also use a letsencrypt certificate. Can I simply change the domain name of the site to the new name and enter the old name as an alias or will this cause problems? Greetings Bernd
