Etcd cluster upgrade not working?

[ryanj]

In the "Scale the Etcd Cluster" section, there is a step that instructs the user to update the spec.version setting to upgrade the datastore from release v3.1.10 to v3.2.13:

oc patch etcdcluster example-etcd-cluster --type='json' -p '[{"op": "replace", "path": "/spec/version", "value":3.2.13}]'

Expected: The following text is provided for the user: "This will take a while, but we will see pods being stopped and created as the version of the cluster is being upgraded."

Observed: The cluster kept running version v3.1.10. I didn't see any of the pods being stopped or restarted by the operator in order to perform the upgrade to v3.2.13

I can't replicate this issue...

When I patch the CR, the pods update to 3.2.13:
