Migration involves using the Migration Wizard to export a copy of your existing mailboxes, messages, and other data, and then import that information into Exchange 2003. 233 Data That Can Be Migrated from Exchange 5.5 Migration Wizard is a tool that is used to migrate mailbox data and simple directory service information. You can use Migration Wizard to migrate the Exchange 5.5 data shown in Table 2. Data that cannot be migrated is shown in Table 3. Table 2 Data that can be migrated from Exchange 5.5 Item Notes Directory information Migration Wizard migrates a subset of the attributes from the Exchange 5.5 directory to the Microsoft Active Directory® directory service user object that was created for the migrated mailbox. 234 Item Notes Mailbox content Migration Wizard migrates the messages and information in the Calendar, Contacts, Deleted Items, Drafts, Inbox, Journal, Notes, Sent Items, and Tasks folders. The folder structure of the Exchange 5.5 mailbox is mirrored in the Exchange 2003 mailbox. Data That Cannot Be Migrated from Exchange 5.5 Table 3 Data that cannot be migrated from Exchange 5.5 Item Notes Inbox rules Inbox rules must be re-created after migration. 235 Item 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. 236 Item Notes Out-of-office messages If a user selects the I am currently Out of the Office option (using the Out of Office Assistant) and migration occurs while this option is selected, the option will be reset. After migration, the I am currently Out of the Office option must be reset. Offline folder files Migration Wizard does not update the offline folder files for each migrated mailbox. Because the offline folder files might be outdated, mailbox users who have offline folders must delete them after migration. 237 Item Notes Offline address books Migration Wizard does not maintain offline address books during migration. Default settings are added to any customized settings. After migration, you must regenerate offline address books and users must download them after regeneration. Profile Migration Wizard does not update the profile of each migrated mailbox. Mailbox users must create new profiles. Personal Address Book Migration Wizard does not update entries in the Personal Address Book stored on a client computer. When you migrate an Exchange 5.5 mailbox, Personal Address Book entries for the mailbox user no longer contain valid addresses. 238 Item 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. Attributes Migrated from Exchange 5.5 Migration Wizard migrates a subset of attributes from the Exchange 5.5 directory to the Active Directory user object for the migrated mailbox. Table 4 lists these attributes. 239 Table 4 Attributes that are migrated from Exchange 5.5 to the Active Directory user object Exchange 5.5 attributes Attribute names in Active Directory Display-Name displayName (also used as cn value) Given-Name givenName Surname Sn Proxy-Addresses proxyAddresses Mail-nickname mailNickname Extension-Attribute-1-15 (also known as CustomAttribute 1 – 15) ExtensionAttribute1 - 15 Initials Initials 240 Exchange 5.5 attributes Attribute names in Active Directory Comment Info Assistant-Name Secretary Telephone-Mobile Mobile Locality-Name L Company Company Text-Country Co Title Title Physical-Delivery-Office-Name physicalDeliveryOfficeName Telephone-Fax facsimileTelephoneNumber . roles Run Exchange 2003 Migration Wizard  Exchange Full Administrator role applied at the organization level  Exchange Full Administrator role applied at the source domain  Exchange. structure of the Exchange 5.5 mailbox is mirrored in the Exchange 2003 mailbox.
