How can all the agent configuration settings be applied to all servers at the same time?
Follow these steps:
1. Open Exchange Migration Project.
2. Select Tools | Defaults.
3. In opened window on left side highlight the agent, eg. "Mail Source Agent"
4. In right pane window specify the settings.
Note: If the auxiliary account for ADAM was changed using the "Project Wizard" or a decisions was made to use another delegated account then press "Select ADAM Server" and specify the account, click "Connect" and then OK.
5. In right pane window in lower part select the checkbox "Apply these properties to all instances of Mail Source Agent".
6. Press OK.
Note: a popup window which reports about errors for some servers is expected and should be ignored as long as the reported servers do not have the selected agents installed.
After the process is finished all config.ini files for all agents (in the example above for the Mail Source Agent) should be updated with new information.
