You can use a control file instead of the configuration wizard to configure SnapManager. The control file support for Exchange Server 2010 mailbox databases is based at the Database Availability Group (DAG) level and not at a member server level.
You can export the configuration settings of a DAG to another DAG or import the configuration settings from another DAG. This is possible by using either a SnapManager snap-in or a SnapManager for Exchange PowerShell cmdlet.
Because all database instances in all member servers of a DAG have to be migrated at the same time to keep database replication operating properly, the control file support for Exchange Server 2010 mailbox databases is DAG based, not member server based. It is not possible to export the configuration of a member server in a DAG to a control file and then import that control file to another member server in the same DAG.
