You'll need /opt/zimbra/ssl/ssl/commercial.keystore from the original. Wouldn't hurt tho have commercial.csr also. You really just need to copy commercial.keystore to the same location on the new server and to /opt/zimbra/tomcat/conf/keystore. Restart tomcat and you should be golden.
One thing I've noticed in doing this is the certs get reset during upgrades, so I know something is missing still, but it does work. I've just learned to keep a backup of all my ssl info and after an upgrade copy them back. |
