#### **Scenario: User can see changes when updated rule is a different rule type**

**Automation**: 1 UI integration test
**Automation**: 1 e2e test

```Gherkin
Given a prebuilt rule is installed in Kibana
And this rule has an update available that changes the rule type
When user opens the upgrade preview
Then the rule type changes should be displayed in grouped field diffs with corresponding query fields
# When tooltip enhancement is added, this step needs to be added to the corresponding test scenario
And a tooltip is displayed with information about changing rule types
