Exchange 5.5 Migration Overview
Migration is the process of moving your existing Exchange 5.5 messaging

system to Exchange 2003. 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outdated, mailbox users who have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.
