Hi Guilherme Teles,Thank you for posting in windows server forums, I believe you have used ADMT tool to migrate users. So what was the error message you received when you tried to perform the ADMT migration ?Have you performed " Test the migration settingsa and migrate later " option and then migrated users ?you should make sure that domain should be in native mode while performing the migration

Hello,in addition to Sainath's information. For not longer existing DCs check:http://support.microsoft.com/kb/555846/en-usor use in AD UC or AD sites and services the new option with deleting the DC which automatically triggers the AD databse cleanup. You still have to cleanup DNS if the servers where DNS server also.for domains:http://support.microsoft.com/kb/230306The steps also apply for Windows server 2008.Best regards Meinolf Weber Disclaimer: This posting is provided "AS IS" with no warranties, and confers no rights.
