You can upgrade Fleet Manager to a more recent version by following these steps:
Create a snapshot of Fleet Manager’s data disk. Take note of the name that you gave the snapshot, this will be referred to as snapshot-name.
Delete the Fleet Manager’s deployment in the Deployment Manager on the GCP console. When prompted, make sure the option to delete all resources created by the deployment is selected.
Follow the guided setup example to deploy the new version of Fleet Manager.
When using either the command line or the yaml config file, add a new element to the “properties” section: “snapshot:global/snapshots/<snapshot-name>” or “snapshot:projects/<project-name>/global/snapshots/<snapshot-name>” if the snapshot is in a different project
Once the deployment is complete, the new version of Fleet Manager will be up and running.
