Setting Up Target Agent Host Account

This section describes how to set the required permissions for the Target Agent Host Account used by Migration Manager for Exchange agents. This account is used to install and run Migration Manager for Exchange agents on the target agent host and to access the license server. The required privileges for the Target Agent Host Account are as follows:

• Membership in the local Administrators group on the license server (unless alternative credentials are used for the license server). If server is located in another trusted forest, the account should have local Administrator permissions on the license server
• Local Administrator permissions on the agent host server.

• The db_owner role on the SQL server where the database resides

• Permission to create, read and write SCP in domain where agent host resides. The SCP object is located in the CN=Exchange Migration Project,CN=QmmEx,CN=Migration Manager,CN=Quest Software,CN=System,DC=eternity,DC=<...> ,DC=<...> Active Directory container.

To set up the Target Agent Host Account, perform the steps described in the related subtopics.

Changing the Default Target Agent Host Account

The default Target Agent Host Account (initially displayed on the Default Agent Host page of the Exchange server Properties) is set when you add the target organization to migration project (see the Registering Source and Target Organizations section of the Migration Manager for Exchange User Guide for details).

If necessary, you can change the default Target Agent Host Account. For that, go to the Agent Management node in the Migration Manager for Exchange Console, and use properties of the corresponding agent host server.
