We have Exchange 2010 in place, trying to install Exchange 2013 in a 2 node DAG. Running Exchange 2013 on Server 2012 R2 as a Hyper-V guest on a 2008 R2 Hyper-V host.
In my ECP under database availability groups for my DAG on my new Exchange 2013 nodes it show 65 ReplicationDagNetworks. I actually only have one replication network and have verified in powershell that replication is using the correct network.
Also the command get-databaseavailabilitygroupnetwork fails with a "could not load file or assembly" error.
Not sure if that is related.
