Manual From Older Versions

Manual From Older Versions#

This section guides you in the upgrade from a Carbonio 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#

  1. A new backup database has been introduced in recent versions of Carbonio. During the upgrade of the Database Node , you must run the following command and then reboot all the Nodes

    # PGPASSWORD=$DB_ADM_PWD carbonio-mailbox-db-bootstrap carbonio_adm 127.0.0.1

  2. 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 server.
