The ancient Sun Fire 280R that's been our DHCP server for about a decade
needs to be out of here, and soon. It's running the stock Solaris 10 DHCP
server software. I'm inclined to let one of our Windows 2008 R2 servers take
over the DHCP duties (although I might be persuaded to go a different way,
e.g. ISC DHCP on RedHat, but DNS is already on Windows so...). This is a
pretty small environment, with only about 130 dynamically-assigned addresses,
all in one contiguous range. I assume there's no way to transport the
current lease information between such disparate servers. Any suggestions on
making the transition go smoothly?
change the lease time to a small value, wait until everyone has new leases
with this smaller value, then swap out the servers when they are all home
overnight.
the only people who will be affected are then ones who are online at the
time you change the server.
