If this does not have a commercial certificate, then don't copy the password. Don't copy the self signed certificate.


NO_SUCH_SERVER errors
make sure hostname on old and new server match. No cheating by looking at name showing on prompt. Actually run hostname command or you may find one computer set to mailserver and the other to mailserver.xxx.com and then won't you be embarrasted for wasting 2 hours on the repercussions :) well... not 2 hours, more like 1/2 hour but it does remind me to verify, verify, verify...
check localconfig.xml on both machines and set hostname referecences the same
ie: search for xxx.com and make mail.xxx.com or xxx.com match

Don't copy extra stuff for good luck, such as the whole data/ldap directory

Fatal error: exception while binding to ports (this one is in zmmailboxd.out log)
You dutifully coped the keystore password from the localconfig.xml file so the new system can't access the NEW keystore anymore.
Copy the one from the old server /opt/zimbra/jetty*/etc/keystore to the new server and set chown zimbra:zimbra keystore and restart zimbra

Always set server up to be the DNS server as well. It will save on grief.
When setting it up, point mx rec and everything else to this server's ip address
Once everything is running correctly, you can set the dns entries to point to the outside firewall.
Make sure to forward LMTP. You can deny outside access, but the server complains if the server tries to access it using the outside address and doesn't get a response
