I'm migrating users from one Zimbra server to another, and for a variety of reasons can't do a wholesale backup/restore of the /opt/zimbra directory. So I've created all the same accounts on the new server as on the old, and am using imapsync to sync up mail folders. I've run into two quandaries though:

1) How can I extract passwords (encrypted) from the old server and set them directly on the new server? When I use zmprov, all I see is "userPassword: VALUE-BLOCKED" instead of the encrypted password. Is there a way to get the password entry?

2) How can I copy over Contacts? The Contacts folder in Zimbra seems to be a special one, so that imapsync isn't able to copy "messages" from one server to the other in that folder... instead, I simply see repeated "NO APPEND failed" messages.
