Upgrade From 24.7 or 24.9#
Carbonio does not have any installer: whenever new versions are released, the Zextras repositories are updated and packages are available for installation along with the other system updates. Therefore, the upgrade procedure is usually a very quick activity, carried out by means of a few commands to be executed.
There are two alternatives to carry out an upgrade: by using Ansible and manually.
The procedure using Ansible is fully automatised and can be executed unattended, without even logging to the Nodes (please refer to Section Prepare the Ansible Environment): you start the upgrade and check back for the outcome at a later point.
The manual procedure requires to login to each Node and issue commands there. You also need to follow the procedure in case there are errors.
We can not provide any estimate on the time required by the upgrade, because various factors may impact the duration, including the number of Nodes, their load, the speed of network connection, and so on.
In some cases, incompatibilities may seldom arise in the upgrade of third-party software, which may lead to some additional manual steps to be carried out. This is true especially in the case of upgrading from older versions, so please check Section Known Issue (Older Releases) under Troubleshooting Carbonio before starting the upgrade.
Hint
For improved security, to prevent any data loss, it is suggested to make a backup or take a snapshot (if you are using an hypervisor) of each Node before upgrading.
