Juju version compatibility matrix
Newer versions of Juju are compatible with older versions, but only up to a point. For each version of Juju, there is a minimum supported agent / CLI client version that it can communicate with. These values are stored as constants in the source code, in the file
upgrades/upgradevalidation/version.go.
For convenience, we have created a Juju version compatibility matrix below. For each version of Juju, this matrix lists its minimum supported agent/client versions.
The minimum supported agent version applies to communication between an older and newer Juju controller, including:
- model migrations
- cross-model relations
The minimum supported client version applies to operations using an older Juju client with a newer Juju controller, including:
- upgrades
- model migrations
