  • Hello,

    Please check Vinod's suggestion.

    Here is a blog for your reference.

    Besides, before you upgrade DAG, these things need to be considered:

     ===========================================================

    1. A really good backup of your environment in place (Databases and Active Directory).

    2. Make sure that all systems that use Exchange Server 2013 support the new CU3 (Backup, Archive and so on).

    3. If the backup software is running, please stop it.

    4. Please use Get-MailboxDatabaseCopyStatus cmdlet to make sure your database copy is healthy.
