However, Migration Wizard does not overwrite existing Active Directory information. Only blank fields or multi- value fields are populated.  If a user object does not have a mailbox, a mailbox is created.  If matching contact objects exist, Migration Wizard deletes the contact object. Selecting the Accounts to Migrate To select the accounts you want to migrate, use the Account Migration page of the Migration Wizard. Furthermore, you can use the Windows Account Creation and Association page to view any matching accounts. If necessary, on this page, you can use the following options to change the account information:  To undo a matching account that appears in the Existing Windows Account column and then create a new user account, use the Create New Account page. 573  To edit the Full Name and Login ID for a new Windows account, double-click the account to open Mail Account Properties, and then edit the account information. Note: To undo a hard match (that is, e-mail addresses that match) return to the Account Migration page and clear the user. Then, before you begin the migration process, edit the user's e-mail address in the migrating messaging system or edit the e-mail address of the Active Directory user object so that the addresses no longer match. Permissions Table 3 lists the permissions necessary to run Migration Wizard 574 Table 3 Source and target forest permissions for running Migration Wizard Forest Required permissions or roles Target forest administrator  Exchange Full Administrator role applied at the organization level  Domain Administrator  Local Machine Administrator Source forest administrator  Exchange Full Administrator role applied at the organization level Data That Can Be Migrated from Exchange 2000 or Exchange 2003 Table 4 lists the data that you can migrate from one Exchange 200 or Exchange 2003 forest to a separate forest. Table 5 lists the data that you cannot migrate. 575 Table 4 Data that can be migrated from Exchange 2000 or Exchange 2003 Data Notes Directory information Migration Wizard copies the user information from your source directory, searches Active Directory to find matches, and adds the information to the matching object or creates a new object based on the migrated information. Mailbox content Migration Wizard migrates the messages and information in the Calendar, Contacts, Deleted Items, Drafts, Inbox, Journal, Notes, Sent Items, Tasks, and custom folders. Server side rules Migration Wizard migrates any server side rules the user has configured. 576 Data Notes Out-of-office messages When run in clone mode, Migration Wizard migrates out-of-office messages for each mailbox. Offline folder files When run in clone mode, Migration Wizard retains the user's offline folder files (.ost). Offline address books After migrating your user's mailbox their offline address must be updated. For more refer to the Exchange Profile Update tool section in this topic. 577 Data That Cannot Be Migrated from Exchange 2000 or Exchange 2003 Table 5 Data that cannot be migrated from Exchange 2000 or Exchange 2003 Data Notes Public folders Migration Wizard does not migrate either public folder content or the public folder hierarchy. This includes messages and other items (such as forms) stored in public folders. Public folder permissions Migration Wizard does not maintain public folder properties or permissions for migrated mailboxes. After migration, migrated mailboxes must have their public folder permissions updated in the destination site by the administrator. 578 Data Notes Signature validation Migration Wizard does not maintain signature validation. Users with advanced security might not be able to validate the signatures on messages that were sent before migration. Encrypted messages Existing encryption keys will not be available after migration. To avoid the risk of losing access to messages if their keys are lost, users should decrypt encrypted messages before migration. Reducing Data to Be Migrated If possible, before you run Migration Wizard, you should reduce the amount of data to be migrated. You can reduce both directory information and mail data. You can do this by: 579  Instructing users to delete old mail and calendar data.  Instructing users to delete old contact data.  Deleting old mailboxes from your Exchange server.  Advising users not to log on to the mailbox during the migration process. Furthermore, during the migration process, you can also use Migration Wizard to reduce the amount of data that you migrate. On the Account Migration page, ensure that only the user accounts you want to migrate are selected. Then, on the Migration Information page, use the following options to specify what data should be migrated: Note: If you run Migration Wizard in clone mode, you cannot filter data by date range or by a specific subject.  To migrate messages within a date range, select the Migrate Mail messages within a date range check box. Then, to specify a date 580 range, type a start date in the Date Range box and an end date in the To box.  To avoid migrating mail messages with specific subjects, such as a list of words or letters, select the Do not migrate mail messages with specific subjects check box. Then, next to Subject List File, click Browse to locate the file that contains the subjects you want to filter. Note: The files in Subject List File must be saved in Unicode file format. Migration Wizard Modes There are certain features that are available only when you run Migration Wizard in a specific mode.
