The ILM sample code demonstrates how to sync source mailbox as Mail Enabled Users (MEU).
The problem with this sample code is was only designed for migration between two forests. My customer wishes to pre-stage user accounts from 2 forests into a new forest meaning I have two source forests! In the OneWaySync.xml file by default we have:
<?xml version="1.0" encoding="utf-8" ?>
<config>
<TargetOU>ou=MaiLboxmoves,DC=targetdom,DC=exchange,DC=contoso,DC=com</TargetOU>
<SourceMAName>Source Forest</SourceMAName>
<TargetMAName>Target Forest</TargetMAName>
</config>
I worked with a Microsoft FIM (Forefront Identity Manager) expert named Tracy Yu and together we made changes to the sample code and recompiled a new DLL to account for multiple source forests.
The file we needed to edit was Microsoft.Exchange.Sample.OneWayGALSync.MVRules.dll. The source code for this file is located under the solution folder under the sample ILM sample code package in a file named Microsoft.Exchange.Sample.OneWayGALSync.MVRules.cs. Here is our new code - in red are any changes made:

Now when we can create two source domains in our OneWaySync.xml file for two source management agents.
<?xml version="1.0" encoding="utf-8" ?>
<config>
<TargetOU>ou=MaiLboxmoves,DC=targetdom,DC=exchange,DC=contoso,DC=com</TargetOU>
<SourceMAName>Source Forest 1</SourceMAName>
<SourceMAName1>Source Forest 2</SourceMAName1>
<TargetMAName>Target Forest</TargetMAName>
</config>
Thanks Tracy!
