Checking System Requirements

Caution: Any computer that does not meet the requirements should be upgraded before installing Migration Manager for Exchange components.

Migration Manager for Exchange uses the following Exchange-specific agents involved in the process of migration to Exchange 20102013 organization:

Transmission Agent (NTA)
Migration Agent for Exchange

Agents work on agent host servers. Agent host is a stand-alone server. It can be located in another forest.

Note: Agent hosts for mail and public folder synchronization must be different as additional software required for MAgE and for PFSA/PFTA to perform those synchronization types cannot be installed on the same computer.

For detailed information about system requirements for agent hosts, see the Exchange Migration Agents section of the System Requirements and Access Rights.

Target Exchange 20102013 Organization Considerations

The Migration Manager for Exchange console shows only those servers from target Exchange 20102013 organization that host the Mailbox role. This is required because only servers with actual data are considered for migration.
The Exchange Autodiscover service must be properly configured and run in your Exchange 20102013 organization. For information on Autodiscover for Exchange 20102013, go to http://msdn.microsoft.com/en-us/library/exchange/jj900169.aspx.
SSL certificates enabled on Exchange 20102013 Servers of the target organization should be signed by a trusted publisher. If you use self-signed certificates, you need to log on to each agent host under the Agent Host Account and add certificate to the Trusted Root Certification Authorities and Trusted Publisher lists.
The Exchange 20102013 Calendar Repair Assistant (CRA) should be disabled during the migration period.
To migrate Recoverable Items subfolders the In-Place Hold and Litigation Hold features should be disabled on the target during the migration. Refer to User Guide for instructions on how to prepare your environment and enable this feature.
