If we made any change to Blue print copy and want to reflect the changes to Live-copy as well, then we have to use Rollout page from the Sidekick. Then the changes will get reflected under Live-copy.
So, the changes are reflected and captured under jcr:content of the live copy. Here if we want to capture the RollOutPage event in aem using the java, we can use following code as reference.
Note: The following code is just for reference.
