Upgrading Spinnaker is a two step process. First, select the target version. Then, apply your change.
If you want to change Spinnaker versions using Halyard, you can read about supported versions like so:
hal version list
And pick a new version like so:
hal config version edit --version $VERSION # this will update Spinnaker hal deploy apply
