We are at a point in our upgrade where we get this in the log.

Fri Jul 26 18:33:32 2013 *** Running as zimbra user: /opt/zimbra/bin/zmlocalconfig -f -e ssl_allow_untrusted_certs='true' 2> /dev/null
Fri Jul 26 18:33:32 2013 Error: /opt/zimbra/data/ldap/ldap.bak is empty
Fri Jul 26 18:33:32 2013 UPGRADE FAILED - exiting.

We have a backup file from around the time we started (I assume created by the uninstall/install). Support is gone for the day so I was hoping to catch someone here. We did try copying the backup file to ldap.bak but the install still fails at this point.

Any ideas?
