we have a cron job that rebuilds both daily

The SIDs on several hundred GB worth of files and dirs will almost all
be from the old domain. The old domain controller will be shutdown,
but there will be a SID history associated w/(almost) each domain user
account and group that was in the old domain. This SID history will be
saved on the domain controler in the new domain.

So, if you run 'ls -l' in one of these directories whose files have SIDs
from the old domain, I'm wondering if the SID history mechanism will
work, showing the matching user or group in the new domain?

I'll let you know what our tests show in the next few weeks.
