From Older Versions#

This section guides you in the upgrade from a Carbonio CE version older than 25.9 to the latest available version, 25.12.0.

Note

Upgrading from very old versions should work, but may require a lot of manual tasks to be carried out before, during, and after the procedure, and might become an extremely long and error-prone process.

To perform the upgrade, first follow all the steps documented in Manual From Previous Version, then apply the additional actions described below.

Checklist for old versions#

The memcached software does no longer require a special bind address, so after the upgrade you need to execute a command to clear its configuration on the Proxy Node. After the upgrade of that Node, before rebooting, execute command as the zextras user
```
zextras$ carbonio prov -l ms $(zmhostname) zimbraMemcachedBindAddress ""
```
Then reboot the Node.
If you are upgrading from older releases, two packages have been renamed. You must update them if they are still present in your infrastructure:
- carbonio-message-dispatcher carbonio-message-dispatcher-ce
- carbonio-storages carbonio-storages-ce

Steps to upgrade renamed packages

Ubuntu 22.04

# apt remove carbonio-storages
# apt install carbonio-storages-ce

RHEL 8

# dnf remove carbonio-storages
# dnf install carbonio-storages-ce

Ubuntu 24.04

# apt remove carbonio-storages
# apt install carbonio-storages-ce

RHEL 9

# dnf remove carbonio-storages
# dnf install carbonio-storages-ce

Run the pending-setups command to update Mesh information and reboot the node.
