As part of a large site migration, I need to copy over numerous (about 50) SSL certificates for different sites.
I have tried to export them on the current server and then import them on the new server, with no success. I can get everything to load and work correctly, but if I run SSLDiag on the new server, I get the error "#WARNING: You DON'T have a private key that corresponds to this certificate".
I can't find any way to import the key along with the certificate. Do I need to renew each certificate, and if so, is this something that would cost money?
Edit: these servers do not have the connectivity required to use the "copy or move cert" option in the SSL wizards.
Edit2: By renewing the cert, does it invalidate the one on the old server?
