Upgrading to 4.2 Trilio charms¶
The Trilio charms are now managed in channels within the CharmHub. The Trilio charms have a track which corresponds to the version of Trilio they are compatable with, so each charm has a 4.0, 4.1 and 4.2 channel. The charms are also compatable with the previous version of Trilio so that they can provide an upgrade path.
For example if an existing deployment is using Trilio 4.1 then the first step is to upgrade to the 4.2 charms which will provide backward compatability with 4.1.
juju refresh --channel 4.2/stable trilio-dm-api
juju refresh --channel 4.2/stable trilio-wlm
juju refresh --channel 4.2/stable trilio-data-mover
juju refresh --channel 4.2/stable trilio-horizon-plugin
Once all charms have been upgraded the Trilio packages can be upgraded to 4.2.
juju config trilio-dm-api triliovault-pkg-source='deb [trusted=yes] https://apt.fury.io/triliodata-4-2/ /'
juju config trilio-wlm triliovault-pkg-source='deb [trusted=yes] https://apt.fury.io/triliodata-4-2/ /'
juju config trilio-data-mover triliovault-pkg-source='deb [trusted=yes] https://apt.fury.io/triliodata-4-2/ /'
juju config trilio-horizon-plugin triliovault-pkg-source='deb [trusted=yes] https://apt.fury.io/triliodata-4-2/ /'
