Hi, I had obtained a class 1 certificate from StartSSL following howto on my previous Fedora ISPConfig3 installation. Now I've changed to Debian 6 and ISPConfig3 following perfect-server-debian-squeeze-with-bind-and-dovecot-ispconfig-3 and want to use my certificate again. Can I do this? It is the same hardware but different OS so I think there may be a problem. I tried at StartSSL.com to take out another certificate for the same FQDN but it wouldn't let me, said that e.g. server1.example.com certificate already exits. It suggested that I either revoke my current certificate ($25) or apply for a class 2 certificate. Can I use my existing certificate? I need to get rid of the browser cert warnings. Can I go to a class 2 without having to revoke my class 1? Could someone please point in the best direction? Thank you.
