Second
Scenario
This
scenario describes how to create a
two-way recipient Connection Agreement
between an Exchange Server 5.5 computer
that is running in a separate Windows NT
4.0 domain and a new Windows 2000 Active
Directory domain. This scenario requires
at least a one-way trust relationship in
which Windows 2000 Active Directory
trusts the Windows NT 4.0 domain.
However, to ease administrative effort,
a two-way trust relationship is
recommended.
Important: if your migration
strategy is to have users log on to your
newly-created Active Directory, then you
can run the ADMT before you create your
two-way recipient Connection Agreement.
If you run a domain migration tool that
migrates SidHistory such as ADMT before
you create your two-way recipient
Connection Agreement, you do not have to
run the ADClean Utility. ADMT settings
allow the Administrator to create
enabled users with which a valid 5.5
mailbox can match.
To create
a two-way recipient Connection Agreement
between an Exchange Server 5.5 computer
that is running in a separate Windows NT
4.0 domain and a new Windows 2000 Active
Directory domain:
-
Perform all of the steps in the
"First Scenario" section of this
article.
-
Start
the Windows 2000 Active Directory
Users and Computers snap-in, and
then confirm that Exchange Server
5.5 users have been replicated as
disabled users. Note that these
objects are located in the default
import container that is specified
on the From Exchange tab of the
Recipient Connection Agreement.
Important: Do not enable
these disabled users. These accounts
are only place holders for the
Exchange Server 5.5 mailboxes; these
accounts are not security
principals, and are not meant to be
logged on to.
-
Determine which one of the following
methods you want to use to migrate
your user accounts to Windows 2000
Active Directory:
-
Upgrade the Windows NT 4.0 domain to
Windows 2000.
-
Use
the Active Directory Migration Tool
(ADMT) to migrate users, including
SidHistory.
-
Use a
third-party migration utility that
supports SidHistory migration.
-
After
you migrate the users to Windows
2000 Active Directory, you can run
the Active Directory Cleanup Wizard
(ADClean) to merge the mail
attributes from the ADC-created
place holder accounts with your
newly migrated users.
