Running Migration Wizard in Default Mode

In default mode, Migration Wizard performs a mail merge of the

messages in your mailboxes If an existing mailbox exists, the mailbox data is not duplicated Before copying a message, Migration Wizard

checks the last modification date of the message; if the target copy is newer than the source copy, the wizard does not copy the message This

is useful for incremental mailbox copies or failed migrations For example,

if your last migration failed before completion, Migration Wizard now skips the existing messages that were copied successfully You can also use Migration Wizard to import the messages that were delivered to the

source mailbox during or after the last migration

Limitations of Default Mode

When using Migration Wizard in default mode, consider the following limitations associated with moving mailboxes across forests:

 If you run Migration Wizard in default mode, your users lose their ost files after you migrate mailboxes As a result, your users must

synchronize their ost files again

 If the target message was previously copied by other tools, Migration Wizard may not function unless those tools preserve the

PR_SEARCH_KEY

 The Migration Wizard log file does not output the counters for skipped and replaced messages

 Delegate permissions are not preserved during a cross-forest move

 Published certificates are not migrated during the move In addition, you cannot recover Key Management Service certificates after a move

To be recovered, the certificates require a domain name

 Client-side rules are not preserved during a cross-forest move

Running Migration Wizard in Clone Mode

Running Migration Wizard in clone mode allows you to preserve your user's data, Inbox rules, and user ID's in their mailbox

Also, if you are using Cached Exchange Mode, use Migration Wizard in clone mode to migrate your user mailboxes (to preserve your user's ost files), and then use the Exchange Profile Update tool (Exprofre.exe) to

update your user's Outlook profiles For more information about

Exprofre.exe, see, "Exchange Profile Update Tool" later in this topic

Limitations of Clone Mode

The following are limitations associated with moving mailboxes across forests Plan for these situations, and notify users of the steps they must perform before and after the move:

 If you are using Cached Exchange Mode, it is recommended that you use the Exchange Profile Update tool after migrating your mailbox to preserve your user's ost files

 For Migration Wizard to run in clone mode, a user target mailbox

cannot exist in the destination organization If a user target mailbox does exist, and the user has logged on to the mailbox, Migration Wizard

switches to default mode

 Migration Wizard does not support filtering by date and subject

 The Migration Wizard log file does not output the counters for skipped and replaced messages

 Delegate permissions are not preserved during a cross-forest move

 Published certificates are not migrated during the move In addition, you cannot recover Key Management Service certificates after a move

To be recovered, the certificates require a domain name

 Client-side rules are not preserved during a cross-forest move

Preserving Offline Folder Store Files

One of the new features in Outlook 2003 is Cached Exchange Mode In Cached Exchange Mode, Outlook 2003 uses an offline folder store file (.ost), which is usually stored on the user's workstation If you run

Migration Wizard in default mode, your users lose their ost files As a result, users must synchronize their ost files again Depending on your network speed, hardware configuration, number of users, and other

factors, re-synchronizing ost files can be time consuming and

performance intensive You can preserve the user's ost file by running Migration Wizard in clone mode You can then use the Exchange Profile Update tool (Exprofre.exe) to update your user's Outlook profiles

Note:

To run Migration Wizard in clone mode, at the command prompt, type

D:\Program Files\Exchsrvr\bin\mailmig.exe /m (where D:\Program

Files is the drive on which Exchange 2003 is installed) For more

information about how to run Migration Wizard, see "Running

Exchange Migration Wizard" earlier in this topic

For more information about Cached Exchange Mode, see Configuring

Using the Target Address with Migration Wizard

During the migration, if the mailbox is instantiated or initialized by

incoming mail, clone mode is cancelled Specifically, the target address prevents the migrating mailboxes from instantiating or initializing

Migration Wizard moves mailboxes in two stages: First the wizard creates the users and mailboxes, and then it initializes the mailboxes and clones the mailbox data If the mailbox receives mail before Migration Wizard initializes it, the mailbox is initialized, clone mode is cancelled, and

Migration Wizard switches to default mode

To prevent this, you can run Migration Wizard in batch (command-line) mode with the target address command The target address command takes the address of the source mailbox and stamps it with a temporary proxy address This causes any incoming mail to be delivered to the

source mailbox You can then run Migration Wizard again, in default

mode, to recover the mail data from the source mailbox After the

migration is complete, Migration Wizard clears this temporary proxy

address

Note:

Using the target address match feature in Migration Wizard is available only when running Migration Wizard in batch mode For more

information about using the target address in command-line and batch file migrations, see Batch File and Command Line Migrations for

Canceling Migration Wizard

If you cancel Migration Wizard before completion with the intent of

running the operation again, the directory will still contain some or all of the user objects and mailboxes Therefore, because some or all of the user objects and mailboxes already exist, Migration Wizard run in default mode (instead of clone mode) the next time you start it To avoid this situation, after you cancel Migration Wizard, manually remove the user objects from the directory and the mailboxes from the mailbox store

before running the wizard again

Exchange Profile Update Tool

The Exchange Profile Update tool (Exprofre.exe) is a stand-alone

executable file that automatically updates users' Outlook profiles, allowing users to log onto their relocated mailboxes after the mailboxes have been moved across Exchange organizations or administrative groups To

update the default Outlook profile to reflect the new information, you must run Exprofre.exe on each client computer It is recommended that you use a logon script to run this tool

Download the Exchange Profile Update tool from the Downloads for

Exchange 2003 Web site (http://go.microsoft.com/fwlink/?linkid=25097)

The Exchange Profile Update tool is supported when used in conjunction with the following operating systems and applications:

 Microsoft Windows® 2000 (all editions)

 Microsoft Windows XP (all editions)

 Windows Server 2003 (all editions)

 Outlook 2003 and all earlier versions of Outlook

Note:

Exprofre.exe does not run if Outlook or another MAPI application is

running on a client computer A warning appears stating that Outlook must be closed to run the tool

Exprofre.exe uses information from Active Directory and the current

default Outlook profiles to perform the following steps:

 Back up the default profile

 Look for an X.500 e-mail address indicating that the mailbox has been moved

 Update the default profile with the new user and server properties

 Reconfigure the default profile with the new RPC over HTTP front-end server name (optional)

 Clear the user's nickname file (optional)

 If the version of Outlook is earlier than Outlook 2003, delete or rename the offline folder store (.ost) file

 Delete or rename the Favorites (.fav or xml) file

Note:

Exprofre.exe updates only the default profile Exprofre.exe does not

create new profiles; it only modifies existing profiles

If the tool does not complete successfully, Exprofre.exe creates a backup profile before it modifies the default profile The backup profile name

consists of the old profile name with "backup" added to the end For

example, if the default profile name is "Ted Bremer," the backup profile name is "Ted Bremer backup." If it is necessary to revert to the backup profile, you must ensure that any file name extensions that have been changed are changed back to their original extension and, if necessary, that the file name matches the backup profile name For example, when the tool creates the backup profile, it renames Ted Bremer's Favorites file

to "Ted Bremer.exprofre." To revert to Ted Bremer's backup profile, you must change the extension of the Favorites file back to fav and the name

of the file to "Ted Bremer backup.fav" to match the backup profile name
