SBS 2000 to 2011, clean AD install, 2 AD on same network with same NETBIOS name?

We are planning on migrating from our existing SBS 2000 server to a new SBS
2011 server sometime soon. Long story short, but we plan on starting fresh
with a new AD. Copy all data & export mailboxes from the old server and
import it all to the new server.

My plan would be to stop/disable DHCP on the SBS 2011 server and plug it
into our network. Both servers would be on the same network until
everything is transferred over, at which point the old server would be shut
down.

My only concern is NETBIOS name. The old AD is named ourdomain.com, while
the new AD will be named ourdomain.local, so I don't think that will be an
issue. But the NETBIOS domain name is OURDOMAIN for both.

Is it a problem to have 2 ADs on the same network with the same NETBIOS
domain name? Don't want to plug it in if it will muck things up.

Thanks!

yes, it will muck things up. No, you can't do that. Copy what you need to
copy to an external USB drive, or a workstation with a big hard disk, or
whatever. But don't try to have both of them on the same network. Please.
