This certainly would be a very large Samba 4.x as an AD DC
implementation, and I do wish you the very best with it.  Please plan
and test carefully, we know it can scale much larger than we ever
imagined, but likewise we know there are issues that we would like to
work with you to address if you hit them.  (For example, we have some
patches for LDB that help it scale more, but we also know that dbcheck
for example really, really doesn't scale).  

So, take advantage of the help on the list, and perhaps bring in someone
to assist with your migration.  

For that size, please stay away from the internal DNS server, as the
issue with deleted objects will really bite you fast, and you probably
want the other features of BIND anyway. 

Also, what is the current environment?  Can you give more detail as to
what you are moving from, and what the clients are?
