Hello all,
I'm following the docs at https://docs.zextras.com/carbonio-ce/html/migration.html#domains-and-accounts-provisioning. In phase two, I need the ldif file to import into CarbonioCE server, but I didn't quite understand if I needed it to migrate the accounts with imapsync, but I tried to generate the ldif file with zmslapcat, https://wiki.zimbra.com/wiki/LDAP_data_import_export
I used the command to export the ldif file
/opt/zimbra/libexec/zmslapcat /tmp
And to restore:
root@mail:~# /opt/zextras/common/sbin/slapadd -F /opt/zextras/data/ldap/config/ -v -l ldap.bak
64dcd973 The first database does not allow slapadd; using the first available one (2)
64dcd973 mdb_id2entry_put: mdb_put failed: MDB_KEYEXIST: Key/data pair already exists(-30799) "cn=zimbra"
64dcd973 => mdb_tool_entry_put: id2entry_add failed: err=-30799
64dcd973 => mdb_tool_entry_put: txn_aborted! MDB_KEYEXIST: Key/data pair already exists (-30799)
slapadd: could not add entry dn="cn=zimbra" (line=1): txn_aborted! MDB_KEYEXIST: Key/data pair already exists (-30799)

Closing DB...

Is there any procedure recommended by CarbonioCE to generate this ldif? Or is this step really necessary?
Thanks

Sorry for your trouble.
Can you please tell me whether both of your server has same hostname or not?
Also, take a look at this blog:

I've tried to imapsync but i'm facing the error;
****** could not append ( Subject:[LIGHTMAX-PRODUTORES/DISTRIBUIDORES FIBRA OPTICA], Date:["04-Jul-2023 14:55:39 +0100"], Size:[18033379], Flags:[] ) to folder INBOX: Error sending 'APPEND INBOX () "04-Jul-2023 14:55:39 +0100" {18033379}': 25 BAD maximum message size exceeded
The most frequent error is ERR_APPEND_SIZE. The destination server refuses too big messages. Use --truncmess option. Read https://imapsync.lamiral.info/FAQ.d/FAQ.Messages_Too_Big.txt
It look's the attachment or the message is exceeding configured message size or attachment size. How can those values can be changed?
Thanks

Hi @pmedeiros,
Check out the code section, i have inserted my comment in it also,

Hope it helps.
Thanks and regards,

Thank you, look's it solved.
If you've the chance to test on development, when those errors occurs using imapsync, the services amavis and antivirus stop working
Thank you
Hi,
I am glad that the issue is solved.
I will try to look into the amavis and antivirus stopping issue.
Thanks for the suggestion.
Have a good day🙂

Thanks for your help, I changed the migration strategy and started using zmprov commands to export and import accounts. I used the follow howto https://community.zextras.com/how-to-use-script-to-migrate-zimbra-to-carbonio-carbonio-ce/ thanks
