(All following comments are about the DHCP server)

I happened to hate the GUI that came with the DHCP server, and always
relied on the dhtadm and pntadm commands ...

I assume that the ISC version will not use these commands, and will
probably not be able to talk to the same datastores as the Sun version

if the commands are different, or the datastores are not
accessible/convertible then I would advise against replacing the Sun
server with the ISC server, but look instead to changing the
svc:/network/dhcp-server:default to svc:/network/dhcp-server:oracle
and creating a new ISC svc:/network/dhcp-server:isc or something

If the ISC is not a drop in replacement and someone upgrades they will
find that their server no longer works, and being a DHCP server will
find that their network also no longer works.
