Self-signed certificates vs. server migration


After some probably hardware-induced trouble with my public server (see this thread), I've decided to purchase another one with better hardware specs.

I'm currently busy migrating everything: static web sites, content managements systems, mail accounts, etc.

I'm using SSL with self-signed certificates on a couple of things, and right now I'm wondering: can I just copy these over from one machine to another? I'm moving all the hosted domains, but is trouble to be expected with the certificates if the machine's IP is different? As far as I can figure out, clients will eventually get a warning in their web browser about a security exception. Correct me if I'm wrong.

i think it's associated with a domain name, not IP addresses

yes, it's important the only common name.

But for public servers I suggests to not use a selfsigned certificate.

You can obtain an official signed certificate for free at
