<br>
There was similar query not to long ago on the list but I will be
darned if I can find it. I seem to remember step by step
instructions on completing a move to a new server, maybe I was
dreaming. :-(<br>
This was as close as I found which may be helpful, move the leases
file to the new server and verify if version differences.<br>

<div dir="ltr">Thanks Patrick. I don't know how to handle that.
Not sure how smart dhcp is to detect such a condition or how
long it would take for things to sort itself out.
<div>The default-lease-time in the subnet declaration is 600.
Is there a preferred way to handle this? </div>

<b>Subject:</b> moving subnet to another server<br>
<br>

<div dir="ltr">Hi.
<div><br>
</div>
<div>I'm planning on moving a subnet over to
another server and am not sure what kind of
devil hides in the details. </div>
<div><br>
</div>
<div>The subnet is 10.x.x.0/18 and it is very
busy. Its a subnet devoted to a test harness
of servers that go up and down a lot putting
a big load on dhcpd and named (using ddns).</div>
<div><br>
</div>
<div>Along with the dhcpd change the new dhcp
server will also serve as a dns server for a
new domain. </div>
<div><br>
</div>
<div>To implement the move I have a new dhcp
server I plan to remove the subnet
declaration from dhcpd.conf off the old
server, add it to the new server, then
restart dhcpd on the old server, and start
dhcpd on the new server. </div>
<div><br>
</div>
<div>What I am wondering about is what to
expect for the behaviour of the dhcp
clients. How disruptive might this be?</div>
<div><br>
</div>
<div>Thank you.</div>
