I currently have a newly installed Carbonio server. I also have a corrupted old zimbra 8.8.15 server that was the active server until it recently stopped working due to ldap no longer starting successfully. I've tried many ways to do a clean migration but I've only been able to migrate user names, and distributed lists successfully. My main challenge now is to migrate the 800 gig store. I need a way to import all the existing mail on the old server without the use of ldap. I have already imported all accounts with their existing old IDs.I have total access to both servers and they are on the same local network. I've been on this for weeks. Any will be much appreciated
do you have any log that shows were the errors come from ? (there must be some ... )
are your ssl certificate up to date ?
I guess imapsync won't works if there is no ldap.

Right - I forgot it need credentials for each user. I'd be looking into why LDAP has failed then.
