In current Oracle ODSEE to OUD Directory migration we have an application that is currently dependent on the "nsunqueID" value of the current source "Oracle ODSEE" LDAP server. We have now migrated to OUD LDAP instance and are looking for a method to maintain the migrated schema from ODSEE --> OUD , specifically maintaining the value of the "nsuniqueID" (ODSEE) to the "entryUUID" attribute of the OUD instance . Application has now changed to reference new OUD instance , with use of the application OUD API. Application is now looking for the "entryUUID" attribute value to match that of the previous defined "nsuniqueID" attribute in ODSEE . Any assistance with this approach would be appreciated .
