Why Use Trusts?
We recommend that you establish two-way external trusts between each source and target domain that will participate in migration.
If the forest functional level in both source and target forests is set to Windows 2003 or higher, you can establish forest trust between the forest root domains.
Trusts make it possible to resolve objects’ security identifiers (SIDs), which in turn helps to distinguish objects and enable you to check whether everything is going right. Trusts also help provide co-existence of the source and target environments during the migration process, including uninterrupted access to the resources for both switched users and users not yet switched.
NOTE: Remember that external trusts between Active Directory domains that belong to different Active Directory forests are not transitive. You should establish trusts between each source Active Directory domain and target Active Directory domain individually.

The migration scenarios described in the Basic Migration Steps topic assume that trusts are established between the source and the target domains.
