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🙂

Regards,

Sharif

If you've the chance to test on development, when those errors occurs using imapsync, the services amavis and antivirus stop working

Thank you

I've tried to imapsync but i'm facing the error;

****** could not append ( Subject:, Date:, Size:, 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

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

Hi @ricardobarbosams,

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:
https://community.zextras.com/how-to-use-imapsync-to-migrate-zimbra-to-carbonio-carbonio-ce/

Thanks

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:
