What's a "client server"?

Then copy the host keys over from the old server to the new one.

They're typically in /etc/ssh/ssh_host_*key* or /usr/local/etc/ssh_host_*key*
(the location is configured at compile time).

Make sure the permissions are correct on the new server.  You don't want
the private keys to be readable.
