I want to export Active Directory objects from domain to a different domain. However when I tried to export using the command ldifde everything was completed successfully but when I tried to import the exported file from the mentioned process using the ldifde -i switch it gives me this error:

Add Error on line 2: unwilling to perform
The Server side eorror is " the specified instance type is not valid."
0 entries modified successfully.
An Error has occurred in the program

Any help please
