How to synchronize/Update single attribute from AD to OID for all users

Hi,

I have a requirement to synchronize to "department" attribute from AD to OID for all users. I updated DIP mapping profile like below and ran manageSyncProfiles update.

department: : :user:departmentNumber: :inetorgperson:

manageSyncProfiles update -h ****** -p 7005 -D weblogic -pf AD2OID -params "odip.profile.mapfile  AD2OID.map"

After I ran above command, department attribute is still null value. Is there any way to synchronize/update  the this attribute with affecting current functionality and users.

In my DEV environment, i deleted all existing users using bulkdelete  and ran syncProfileBootstrap. user attributes are  updated for all users. But i don't want to do in our UAT and Production environments because It was integrated with other environments.
