RE: Question about merging a foreign domain to a forest

Hello,

Thanks for your post.

It is possible to merge two Windows 2003 forests or migrate a domain from
one forest to another forest. I agree with Simon that ADMT is the correct
tool for inter-forest migration.

You can download ADMT from the link below:
Windows 2000 Active Directory Migration Tool
http://www.microsoft.com/windows2000/downloads/tools/admt/default.asp

For more information about ADMT, please refer to:
Active Directory Migration Tool Overview
http://www.microsoft.com/windows2000/techinfo/planning/activedirectory/admt.
asp

First, you need to create trust between win2k3 and win2k3, to win2k3, it is
a inter-forest trust. You need to refer to the following KB to migrate
SIDhistory and password:

How to Troubleshoot Inter-Forest sIDHistory Migration with ADMTv2
http://support.microsoft.com/default.aspx?scid=kb;en-us;322970

How to Troubleshoot Inter-Forest Password Migration with ADMTv2
http://support.microsoft.com/?id=322981

Second, after installing ADMT on the target domain's PDC Emulator, logon as
the source domain's Administrator and only keep one ADMT host machine and
you can begin to migrate:

The Recommended Migration Order is listed below for your reference:
1. Trust migration (UI Only)
2. Service account migration
3. Domain Global Group
4. Domain Local Group
5. User migration
6. Computer migration
7. Security translation
8. Report

Third, I would give you a KB article about how to migrate from Windows 2K
to 2K3 and it is same as to migrate from Windows 2K3 to Windows 2K3.

HTH!
