We currently have Active Directory 2003 domain with Sharepoint 2010 and are planning an upgrade to Active Directory 2008 R2.
Sharepoint is currently linked to AD and populates fields like first/last name, Manager, Title ... into an "intranet address book" through the sharepoint portal.
Would the introduction of the first 2008 R2 DC or running adprep have any impact on the user profile service ?
Is it a matter of working out if each attribute name(eg: First Name ...) has changed from AD 2003 to 2008 ?
Any links or tips would be greatly appreciated.
