What is the recommended approach when we have an existing functional AD. We need to import all that data to a new MIM installationfor which the authoritative source of information is HR Feed . How will MIM map the users in FIM portal with the imported users from AD. I believe it should automatically map the user data in metaverse based on objectSID described in the syncrule. Is there any document which can guide for this implementation and any best practices to follow, or precautions to take.
