We are doing a massive migration of users and computers from 60 (+/-) domains into a central enterprise AD (300,000 + users). The question is about user mapping - meaning building the SID history table between source domain and target domain. We are only migrating the SID from source to SID History of destination, no other user attributes will be migrated.
Our question is if we run a sessions with users from one domain then another user session from a second domain, then migrate computers from the first domain, will the profiles be processed correctly on those systems or will the second user session over write the first session?
I hope that makes sense.
Thanks in advance.
