Cross Forest Contact and distribution group migration

Being in the process of Cross-forest migrating users and mailboxes we're looking for a way to migrate the following objects between the forests.

_ Contacts

_ Dynamic distribution Groups

_ Distribution groups

 

We're using ADMT for the migration

thanks

    Use the Exchange Migration Wizard command to migrate contacts and distribution groups across forests, ensuring that empty security groups are pre-created in the target forest:

    New-MigrationBatch -SourceEndpoint LegacyForest -TargetDeliveryDomain newdomain.com-CSVData ([System.IO.File]::ReadAllBytes(C:\migration.csv))
    Need to synchronize AD object SID history
