RE: Upgrade or migrate?

Hello,

Thanks for your post.

First, I would explain the difference between migration and upgrade:

Migration is just as create a new domain and migrate all the resources such
as user account, computer account, user profiles and so on. You need to
use another domain name from the original ones. Upgrade keeps the original
domain. If your original domain is complex and you want to keep it, I
suggest you use the upgrade. By using either method, the settings will be
preserved.

According to your questions, I would give the answers separately:

Q1: If I use ADMT, which is to create trust between new Win2003 and WinNT
PDC and run the migration tool, will everything be preserved after the
migration such that user is transparent and can just log on as normal
without having to rejoin new domain of Win2003?

A: Please refer to the following article about how to create trust between
NT and 2k3.

How To Establish Trusts with a Windows NT-Based Domain in Windows Server
2003
http://support.microsoft.com/default.aspx?scid=kb;en-us;325874

Yes. After migration, those options have been chosen in ADMT that you want
to preserved will be kept and you needn't rejoin new domain.

You can refer to the following article about how to migrate by using ADMT:

Migration Tool

Windows_Server_2003.html

Q2: If I want to use back the old machine, can I just run Win2003 on the
WinNT and perform upgrade? Using this method, will all the user profiles
be preserved including permission for folder setting?

A: You can use the method just run Win2003 on the WinNT to perform an
in-place upgrade. However, we do not recommend you do so for security
purpose. We suggest you perform a not-in-place upgrade as following:

As a kind reminder, please backup the whole system before you take any
action. Also, it is best if you perform the upgrade process during a
non-business time such as the weekend. :)

Performing a "not in place" upgrade
======================

1.Install NT 4.0 BDC on the new box.

2.Promote the BDC to the PDC, which demotes the PDC to a BDC.

3.Do a full backup of the former PDC and remove it from the
network.

4.Upgrade the new PDC to Windows Server 2003.
If you want to expand the boot partition, please refer to the
following KB:

325857 How To Expand the Boot Partition During a Windows Server
2003 Upgrade
http://support.microsoft.com/?id=325857

5.Use the Windows Server 2003 Active Directory wizard to turn on
the Active Directory service. The Active Directory service imports the
existing user accounts, groups, and other settings from the PDC.

6.Run for a test period.

7.If desired you can do a clean installation of Windows Server 2003
on the former PDC, and bring it online as an Active Directory domain
controller.

8.Transfer all Flexible Single-Master Operation (FSMO) roles to the
new Windows Server 2003 domain controller.

9.Verify all directory information has replicated.

tions/00e7f86b-ccd3-4cb8-9a01-bf747241b500.mspx

10.Demote the first domain controller to a member server, and
remove from the domain.


After performing upgrade steps, all the user profiles will be kept
including permission for folder setting.

HTH!
