When establishing replication, some replicated machines show the status of "Deleted". Also, agents from different cores appear as if they are being replicated from the same core.
Each core server must have its own unique core ID. If two different source core servers have the same Core ID then the target core server accepting replication from the two servers will not be able to differentiate between the two servers. This is often caused when core servers are cloned while AppAssure is installed.
To resolve this issue, please uninstall AppAssure from one of the duplicated cores and reinstall it. This will regenerate the core ID as a new, unique ID. Once the two cores have different core IDs, replication will display properly.
