We have a newly-acquired company with an AD domain, say domainB. We have a site-to-site VPN between domainB and the HQ domain - domainA, and also established bi-directional trust relationship between the two forests. Both are in Win 2003 AD level.
We want to merge/integrate/consolidate domainB's AD user accounts into domainA and hope if possible the security/sharing permission etc will also be transferred. How to do that?
