6.1 Starting the Migration Utility

The first time you run the Migration Utility, you should migrate only a small number of mailboxes, so you know how long it takes to migrate mailboxes on your system with its current configuration. This information helps you decide how to implement multiple migration sessions, as needed.

It is not necessary to stop your Exchange system or prevent users from accessing their Exchange mailboxes during the migration. It is possible that some messages arriving during the migration might be delivered to users’ Exchange mailboxes and other messages to users’ GroupWise mailboxes, but because both mailboxes are available to users for a period of time after the migration, this is not a problem.

NOTE:If you are migrating to a GroupWise system on Linux, see Section B.0, Linux Migration before starting the Migration Utility.

  1. Make sure that you have completed all the tasks in Section 4.0, Preparing Your E-Mail Systems for Migration.

    IMPORTANT:The workstation where you run the Migration Utility must have a username and password identical to the one on the Exchange server. Otherwise, you cannot access the Exchange server with the necessary rights.

  2. Log in to the eDirectory™ tree (system worksheet item 6) where you are migrating the Exchange users.

  3. Map a drive to a GroupWise domain directory (system worksheet item 6), preferably to the domain that owns the post offices to which you are migrating Exchange users.

    If the domain is located on Linux, see Section B.0, Linux Migration for additional instructions.

  4. Click Start > All Programs > Exchange Migration Utility > Exchange Migration Utility.
