Hi, never had this problem, but I wonder if this would work, join a 
samba 4 DC directly to the 2K Server and then run 'samba_upgradedns'

Worth a try on a test network, there is this in the middle of the 
'samba_upgradedns' python code:

# dnsprovision creates application partitions for AD based DNS mainly if 
the existing
# provision was created using earlier snapshots of samba4 which did not 
have support
# for DNS partitions
