4. Put DBSVR1 into maintenance mode
1. Copy StartDagServerMaintenance.ps1 and StopDagServerMaintenance.ps1 from c:\upgradepath\scripts to C:\Program Files\Microsoft\Exchange Server\V14\scripts
2. C:\Program Files\Microsoft\Exchange Server\V14\scripts>.\StartDagServerMaintenance.ps1 -serverName DBSVR1 -overrideMinimumTwoCopies

When you run this script, it moves all the active databases to other DAG members. It pauses the node in the cluster, and sets the DatabaseCopyAutoActivationPolicy mailbox server setting to Blocked. The Suspend-MailboxDatabaseCopy cmdlet is run for each database hosted by the DAG member, and the cluster core resources will be moved to another server in the DAG if needed.

When you run this you should get some output like below. This does not mean it failed. If databases are being moved you can verify it through the console.

Run get-mailboxserver - id "servername"  and check the databasecopyautoactiviationpolicy. It should be set to blocked.
