Can i design Active directory OU and hierarchy with this product automatically .

For example: i dont have  OU created in Active Directory but  i want to export them through FIM from oracle database into active directory.

Is it possible.

 i have minimum 100 departments and each department has minimum 120 users.

in my active directory i have around 2500 users with some 50 OU's, but in oracle database i have complete information.

i want to export from oracle db and import it in the active directory
