From Instances, choose All and select the instance you want to upgrade.
Navigate to the Settings tab.
Select the DSS Version menu arrow and choose a version from the list.
Save your changes.

To reprovision an instance after changing the instance settings:
Select Reprovision from the menu.
Select Confirm.

When reprovisioning, Fleet Manager automatically takes a snapshot of the data disk. If something fails during an upgrade, you can change the version back in the settings and revert to the previous state by selecting Reprovision From in the snapshot tab.
Prepare the upgraded instance for users#
When upgrading to a new major version, Dataiku recommends rebuilding code environments and retraining ML models. These operations are not performed automatically by the upgrade procedure. You’ll need to perform these actions manually from DSS or its API.
To prepare the upgraded instance for users:
Rebuild any code environments.
Retrain any ML models.
