Warning: The topology contains more than one Federated Edge Server. This can occur during migration to a higher version of the product. In that case, only one Edge Server would be actively used for federation. Verify that the external DNS SRV record points to the correct Edge Server. If you want to deploy multiple federation Edge Server to be active concurrently (that is, not a migration scenario), verify that all federated partners are using Office Communications Server 2007 R2 or later. Verify that the external DNS SRV record lists all federation enabled Edge Servers.
