Source Forest Becomes an ERF

A popular scenario involving EPW is creation of an Exchange resource forest (ERF) topology instead of a single forest. In this variation of the scenario, user accounts move to another newly-created or existing Active Directory forest, and the target users are supposed to become the new owners of the mailboxes. The source forest remains as an ERF, and the source users are disabled.

Role of EPW

After the migration of user accounts is complete, the users in the target forest have no access to the mailboxes in the ERF. Run EPW against the Exchange server after the migration to make sure that:

  • The target forest user accounts become the new owners of the mailboxes.
  • All delegation-related permissions on the mailboxes are re-aligned correctly to the new users.
  • The new users have the same level of access to public folders that the old users did.

NOTE:

  • You may need to use Active Directory Processing Wizard in the Exchange resource forest after these steps.
  • ERF setup requires EPW only if the source forest becomes an ERF. Making the target forest an ERF involves the use of Migration Manager for Exchange, which automates the permission update work. As long as users’ SIDs can be resolved during the Exchange migration, the permissions will be modified correctly for both source and target users.

Users Change Forest in an ERF Topology

A possible scenario is when users from one forest have mailboxes in another (ERF) forest and are moved to a third forest. The target users are supposed to become the new owners of the mailboxes in the ERF, and the old forest is supposed to be decommissioned.

 

Role of EPW

After the migration of user accounts is complete, the users in the target forest have no access to the mailboxes in the ERF. Run EPW against the Exchange server after the migration to make sure that:

  • The target forest user accounts become the new owners of the mailboxes.
  • All delegation-related permissions on the mailboxes are re-aligned correctly to the new users.
  • The new users have the same level of access to public folders that the old users did.

NOTE: You may need to use Active Directory Processing Wizard in the Exchange resource forest after these steps.

Prerequisites (Exchange Server Processing)

  • For a successful Exchange directory update, you must use an account with the Full Exchange Administrator role for the Exchange organization.
  • For a successful Exchange server update, Integrated Windows authentication must be enabled on Exchange virtual servers and folders.
  • An Exchange 2000 Server update requires Exchange 2000 Server Service Pack 1 or later. It is recommended to use the latest Exchange 2000 Server service pack (currently this is Service Pack 3).

Starting Exchange Update

You can perform Exchange update in several ways. Select the one that best suits your situation.

  • Create an Exchange Processing task and run it from Migration Manager. To create an Exchange Processing task, go to the Resource Processing | Tasks node, and click the Exchange Processing button in the right pane.
  • Create an Exchange processing task, create a setup package for the task, delegate rights to perform this task to another person, and send the package to that person. The delegated administrator will then install the package and perform the Exchange processing as specified in the task configuration. Refer to the Delegating Resource Update topic for more details.
  • Export the INI file with the appropriate settings for Exchange processing, and then create and configure an Exchange Processing task to run in stand-alone mode using this INI file. Refer to the Delegating Resource Update topic for more details.

Regardless of the method you select, Exchange Processing Wizard will guide you through the updating process. Complete the steps given by Exchange Processing Wizard, as described in the related topics.
