Can a sync relationship be established without a trust?

I have a situation where a customer wants to divest and migrate from an old AD Domain to a new Domain in a new Forest.  However the source company is being uncooperative and not allowing any trusts.  I DO have some Admin access into SOURCE domain and delegated control over the OU I want to migrate.  I also have Enterprise Admin permissions on DESTINATION domain.

The Requirements and Installation Guide advises a trust is required for offline domain join, and mentions 'In Order To Receive the Maximum Benefit A Trust Should Be In Place'.   What are the limitations of configuration without a trust?  Can that be accomplished?  I have configured the Binary tree and prerequisites as I can.  However, a sync-only update never completes.  Can you advise  what, if any, sync capabilities can be achieved without a trust?  Thank you very much.

  • Without a trust, you might have to resort to more manual methods of migration. This could involve exporting user, group, and computer information from the source domain and then importing it into the destination domain. Tools like ldifde or csvde can be used for exporting and importing directory objects in AD environments.
