Enterprise Vault Journaling with Exchange Server 2010 DAG

Using Enterprise Vault 11 with Exchange 2013

How do I create a Journaling Task so it will work with a DAG? e.g., Journaling mailbox is currently active on Serv1, I want to ensure EV is able to still pickup the journaled items when the mailbox becomes active on Serv2.

I've read http://www.symantec.com/business/support/index?pag... but when creating a target I can only point to mailbox servers and not a DAG or CAS array.

Thanks
