SIXTHSTAR CARBONIO UPGRADE
The Zextras repositories are updated whenever new versions are released, and packages are then made available for installation with other system updates. Carbonio does not have an installer. As a result, upgrading is typically a relatively short process that only requires a few commands to be run on each Node.
The technique for upgrading consists of a preparatory step followed by the correct upgrade, which is the same for each Node. The successful upgrade will always move Carbonio to the most recent version available, which is presently 23.6.0, regardless of the version that is already installed
Some manual step may be necessary, depending on the upgraded packages and the version you are upgrading from. Before beginning the update, please carefully read section update Checklist to see whether any further tasks are required.
In addition, if the upgrade involves third-party software, incompatibilities could occur, necessitating the completion of some extra manual processes. There is advice to prevent or resolve these problems in the section below under Troubleshooting.
The following roles or packages are affected by this upgrade, and they call for some manual input during the process.
It is advised to create a backup of each Node or to take a snapshot of each Node (if you are using a hypervisor) for increased security and to prevent any data loss.
The Directory Server’s LDAP data is backed up as a first step. The node having the Directory Server Role installed, in our case SRV2 in a Multi-Server installation, should run the tasks listed below.
