  • Copy /opt/zimbra/ssl to /sslbk.
  • Create from the directory /sslbk and transfer it to a holding server.
  • On the destination server stop the zimbra service.
  • As root transfer the file from the holding server to the destination server.
  • Re-name the existing /opt/zimbra/ssl to ssl_old.
  • Un-pack the file to the root directory as /sslbk.
  • Copy the /sslbk to /opt/zimbra/ and rename to ssl so that /opt/zimbra/ssl is re-created using the directory from the source server.
  • cd into the /opt/zimbra/bin directory
  • Deploy the cert ./zmcertmgr deploycrt comm /sslbk/zimbra/commercial/commercial.crt //sslbk/zimbra/commercial/commercial_ca.crt
  • Switch back to Zimbra user and restart Zimbra and then switch back to root and restart the Zimbra service at /etc/init.d/./zimbra restart
