Creating New User Accounts

If you use Migration Wizard to create new user accounts, Migration

Wizard performs the following tasks:

 If matching user objects do not currently exist in Active Directory, user objects are created

 If the messaging system directory you are migrating contains

information that is not already present in Active Directory, that information

is migrated to Active Directory 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

 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

either public folder content or the public folder hierarchy This

includes messages and other items (such as forms) stored in public folders

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

Data Notes

signature validation Users with advanced security might not be able

to validate the signatures on messages that were sent before migration

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:

 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

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

There are certain features that are available only when you run Migration Wizard in a specific mode Table 6 lists the Migration Wizard modes and explains which features are available in each mode
