Here are a few points which you can consider while doing computer migration. These points are applicable to all migrations irrespective of the migration tool (ADMT, NetIQ, Quest etc)
Here is a graphical representation of the high level steps involved in an Active Directory migration using ADMT
Pre-creating user account in the target domain is a common scenario these days due to single-sign-on solution, HR management procedure etc
Rights Management Service (RMS) is an add-on to many RMS aware applications. In this article my main focus is to explain how we can utilize RMS technology with Exchange 2003 and how we can take advantage of RMS technology to increase the email security
I am sure we have all either encountered or heard of this "problem" one time or another if the ISA Server is part of the Active Directory Domain. Is it a problem?

Issue
If you are running your Active Directory in Mixed mode and FSMO roles are on the Windows 2000 or Windows 2003 DC, you won’t be able to see the following built-in groups:
Some of these groups have introduced with Windows 2008 and some these groups have changed name. For example, Certificate Service DCOM Access serves the same purpose as CERTSVC_DCOM_ACCESS in Windows 2003.
However, if you are running Active Directory in Windows 2000/2003 and Windows 2008 mixed mode and your PDC Emulator FSMO roles is not on the Windows 2008 DC, you won’t be able to see these groups. You need to transfer the PDC Emulator FSMO role to windows 2008/Windows 2008 R2 DC (or newest OS) to resolve this issue.
Issue
Active Directory Migration Tool (ADMT) Security Translation Process failed with the following error message in the ADMT log file:
ERR3:7194 Could not open input file C:\Program Files\OnePointDomainAgent\AccountsXXXXX.txt
Cause
This is most likely due to a corrupted ADMT agent (OnePointdomainAgent) installation.
Resolution
Uninstall and reinstall the ADMT agent (OnePointdomainAgent). If you can’t uninstall from the console or control panel, you need to perform a manual removal process.
You can use SC command to delete the agent if needed – SC Delete "OnePointdomainAgent"
Also, make sure the HKLM\Software\Microsoft\ADMT registry key and c:\windows\ADMT Directory are not present after the agent removal.
