Migration is the best time to establish or change a naming
convention. To make global changes to directory information during
migration, do a two-step
migration. After you extract directory and messaging
information from your messaging system (the first step), you can
edit the migration files. Then import the edited migration files to
Exchange (the second step).
Tip You can also edit the
names of users from within Migration Wizard by double-clicking new
user names in the Windows Account Creation and Association
screen; however, if you need to make global changes, it takes less
time to edit the migration files.
To change naming conventions by editing migration files:
In Migration Wizard, use the two-step migration process. The
first step is to extract data from your messaging system: on the
Migration Procedure screen, click Extract migration files
only. Then configure Migration Wizard to extract directory
information. On the Migration Information screen, select the
Information to create mailboxes check box.
Edit the migration
files to make global changes to user names or other directory
attributes. There is one packing list file named for the post
office, a file called Directory.pri that contains the exported
users, and one primary and secondary file for each user. Edit the
Directory.pri file to conform to a new naming convention.
Perform the second step of migration: import the edited migration
files. Users are added to Active Directory with names that
conform to your new convention.
