I have been tasked with transferring SSL certificates from one server to another for a website. I know nothing about this but have been reading that if everything is the same on the 2 servers then I should be able to just copy some files. Otherwise I have regenerate something.
The original server is CentOs machine running apache that has several websites on it. The new server is a CentOs VM also running apache on a different machine. The website has the whole new VM to themselves, they dont share with anyone else. So one thing that is different is the location of their html files. On the old machine their website is under their username and on the new VM they are directly under /var/www/html. Is that something that will make a difference when transferring these certificate files?
Does each site have its own SSL certificate or does the server have one that covers all the sites on it? If so, if I copy the files to a new machine, will it somehow mess up the SSL for the other sites on the old machine?
