SLES DNS and NetWare DHCP

We have had DHCP running on NetWare for some time, with no local DNS
service. The DHCP option 6 is set to a BorderManager DNS proxy.

I just set up a SLES 11 server with named, and it will resolve our local
static IP addresses and forward to OpenDNS. I am using it now, and it
seems to be working correctly. Next step, can I set the NetWare DHCP
server to update the SLES DNS server, or would I be better off setting up
DHCP on the SLES server? My main concerns are transitioning to the SLES
server without disruption, and getting Option 60 for ZFD PXE boot set up
correctly.

TIA
