ADMT Error 0x80004005

I was performing an Active Directory Migration from a Windows Server 2008 DFL/FFL forest with Exchange 2003 to a Windows Server 2008 R2 DFL/FFL forest with Exchange 2010. During the migration I got the following error:

This is due to the difference of the schema versions, some attributes are not migrated to target domain.

The system attribute exclusion list contains two attributes by default: mail and proxyAddresses. ADMT also reads the schema in the target domain. If the target domain schema is further extended, it adds any attributes to the list that are not part of the base schema. Attributes in this list are excluded from migration operations even if the attribute is not specified in the attribute exclusion list.

For more information about this see the article below "Migrating and Restructuring Active Directory Domains Using ADMT v3.1"
