When following migration instructions for 2.5 -> 2.6 there are missing values for label app for the following command which comes from section 2.3 step 5.

DEPLOYED_APP_LABEL=$(oc get dc backend-listener -o json | jq .spec.template.metadata.labels.app -r)

In this instance the migration started from version 2.1 to 2.5 and then attempting to upgrade to 2.6.

When I checked in my fresh 2.5 deployment the value returned from the above command is 3scale-api-management.

Is that the expected value?
