I am trying to upgrade our current Exchange 2013 SP1 (CU4) to CU9. I have a CAS and MBX server in Site A, and a CAS and MBX server in Site B. The MBX and CAS roles run on separate servers. I have a DAG between the two sites and the CAS servers are load balanced behind F5's. The Forest and Domain functional levels are both set to Windows Server 2012 R2. The user account that I am using is a part of Domain Admins, Enterprise Admins, Schema Admins and also a part of the Exchange Organizational Management group. I started on the MBX server in Site B (DR site) and received the following errors/warnings when the prereq check was occurring:
