Not sure if this is still useful for somebody, but here are two scripts, that migrate some more parts: removed link

Mails
Calendar (default name "Calendar")
Contacts (default name "Contacts")
Filters (zimbraMailSieveScript)
Tasks (default Name "Tasks")
Distribution Lists

Some things are still missing, but they might be added later. Contributions welcome.

Thanks to the community for the good resources out there, that helped me to put this together 👍

How to Migrate Zimbra to Carbonio? Manually
First, open the Zimbra desktop client and select the Preferences tab.
Next, select Import/Export and choose “All Folders” to Export.
Now, choose the mailbox to export and hit the Export button.
Lastly, choose the location as per your choice to save the emails.

@arukashi I think we don't support migration of Tasks: our implementation is quite different from Zimbra's, so I can not think of any easy workaround, sorry.

Tasks. Those are in the export, but will not be imported. Error in the logs: "misc - ArchiveFormatter addError:Cannot invoke "com.zimbra.cs.mailbox.MailItem.getType()" because "mi" is null: path=/Tasks/"
Briefcase documents. Same error as with tasks with different path.

Hello. Experience the same problem, still did not managed to import tasks exported from zimbra9 as tgz (no way to export in any other format except zip). Same error. Any workaround for this problem? Thank you

Hi @anahuac !

I am going to start the migration of our ZIMBRA server to CARBONIO, I read the details of the original SCRIPT of BktechBrazil and I think they are fantastic.

The script that you adapted, is it updated to 2024 or do we have to check it again ?

Thanks for sharing.

@anahuac I'll take a look, thank you.

Anyway, i decided just delete unnecessary domains and corresponding stuff right on the destination server.

May I suggest you to try Z2C?

https://www.anahuac.eu/zimbra-to-carbonio-z2c/

It exports all domains together and also separated. It's ready to use =)
