Hi, were you able to resolve your problem ? I also have an Author instance in AEM 6.1 SP1 with cq-6.1.0-hotfix-8651-1.2, cq-6.1.0-hotfix-8651-1.2 & cq-6.1.0-hotfix-9104-1.0the link Activation Tree doesn't appear. In crxde, under replication, there isn't the link..If I try to copy/paste the url of the replication tree page from another AEM 6.0, it doesn't work... Kind regards Yannick
