Zimbra 7.2.0 (Ubuntu 10.04) to Zimbra 8.0.2 (CentOS 6.3) [FOSS Edition]

Hi

Wondering if i could get some help/advice?

In attempting a migration of Zimbra 7.2.0 (Ubuntu 10.04) to Zimbra 8.0.2 (CentOS 6.3) [FOSS Edition], I think I've made the mistake of upgrading the old server from ZCS 7.2.0 (Ubuntu 10.04) to 8.0.2 (Ubuntu 10.04) and then tried to rsync the data to a new server already running Zimbra 8.0.2 (CentOS 6.3).

I used various guides from the wiki for platform independent migrations.

However I now cannot log into user or admin accounts on the upgraded old server now running 8.0.2? The server will also not receive any mail, and gives a '550 5.1.1 user does not exist on this server' error.

I only received the following error during the uprgrade.

Mon Dec 24 20:21:27 2012 *** Running as zimbra user: /opt/zimbra/libexec/zmslapadd /opt/zimbra/data/ldap/ldap.80
50d88f25 ldif_read_file: checksum error on "/opt/zimbra/data/ldap/config/cn=config/olcDatabase={2}mdb.ldif"

Is there a way I can rollback the upgrade of the old server back to ZCS 7.2.0?

Or is there a way I can fix the authentication problems?

I've had a look at the following threads;

Upgrade from 7.2.0 to 8.0 fail with ldap error

https://bugzilla.zimbra.com/show_bug.cgi?id=77623

But not had any joy in resolving the issue.

Any help appreciated?

Some more information.

I deleted the 'cn=config' folder and the 'cn=config.ldif' file in /opt/zimbra/data/ldap/config', and then ran:

/opt/zimbra/openldap/sbin/slapadd -q -n 0 -F /opt/zimbra/data/ldap/config -cv -l /backup/ldap-config.bak

Which completes without any errors.

Users can now login and see there emails as normal. However, when logging into the Admin Console, no user accounts are listed. Likewise running 'zmprov gaaa' lists no accounts.

If I then remove (rename) the data.mdb from /opt/zimbra/data/ldap/mdb/db folder try to run:

/opt/zimbra/openldap/sbin/slapadd -q -b "" -F /opt/zimbra/data/ldap/config -cv -l /backup/ldap.bak

It completes without error:

added: "cn=zimbra" (00000001)
added: "cn=admins,cn=zimbra" (00000002)
added: "uid=zimbra,cn=admins,cn=zimbra" (00000003)
added: "uid=zmreplica,cn=admins,cn=zimbra" (00000004)

added: "cn=zimlets,cn=zimbra" (0000000a)
.........

If i don't remove the 'data.mdb' file and run the command, i receive a whole bunch of Key/data pair already exists errors:

50dc4608 => mdb_tool_entry_put: txn_aborted! MDB_KEYEXIST: Key/data pair already exists (-30799)

but then, users (including Admin) have no login access at all to the webclient or Admin Console (in the case of the admin user acc.) .

I can't figure where I'm going wrong with the import of this LDAP data into Zimbra 8.0.2.?

Have I made an error witht the initial import/transfer of the data.mdb database before LDAP import?

Managed to resolve this by deleting the existing data.mdb file and importing a backup ldap.bak file made before upgrading the old server from 7.2.0 > 8.0.2.

Can now see all accounts in the Admin Console.
