Hello Admin
Please close this topic!
I have resolved all my issues and I now have an up-to-date Carbonio-CE running on Ubuntu 24.04 LTS.

I have rebuilt the server Ubuntu 24.04/Carbonio-CE 25.12 and working.
Domains, Accounts, Aliases, Distribution Lists/Members all migrated onto it.
However, I'm unable to import the emails/contacts/calendar in (.tgz) files.
Carbonio-ce 25.12 doesn't seem to support "zmprov" calls to the mailboxes so the old migration script fails.
Any workaround out there!

Thanks again for for supportive reply

@trelawny

At this point of time, I would suggest following:

1. Install a fresh Carbonio CE
2. Try Imapsync to transfer data

Thanks for the response!

I did the posting late last night hence why it appears truncated. The 27.12 upgrade also upgraded the OS to 24.04 from 22.04, this I wasn’t expecting. I performed the ‘apt full-upgrade’ command as per the documentation.
I have since done some research and was wondering whether a rerun of the official installation script after first remove the software package is an alternate way to go thus ‘preserving data’

Any and all ideas welcomed at this time

Thanks….

Hi,

Considering the sensitivity, I would not recommend to do upgradation of both OS & Carbonio CE at the same time. I would recommend one of the following approaches:

Install Carbonio CE on a Upgraded OS and migrate the data from old system to the new one.
Upgrade the OS first; then upgrade the Carbonio CE.

But regardless of approaches; always take backup/snapshot of your system as Upgrading is a sensitive and critical task.

You could try recompiling perl libraries by cpan but it could also make the issue worst.

I would recommend the first approach, if you do not want to test with your data.

Regards,

Well after over two year trouble free the server is now broken upgrading from 25.6 to 25.12. I'm only able to connect to the sever via SSH.
I followed the upgrade docs to the letter, however its appears Ubuntu was also upgraded from 22.04 to 24.04

zextras@mail:/$ zmcontrol status
Socket.c: loadable library and perl binaries are mismatched (got first handshake key 0xeb00080, needed 0xf380080)

I don't want to reinstall if there's
