<p class="MsoNormal"><span style="font-size: 10pt; font-family: "Verdana","sans-serif"; color: black;">Thanks for your comments Ryan and Justin. They'll definitely help
me build my new cluster. Some comments/questions:</span></p>
<ul type="disc">
<li class="MsoNormal" style="color: black;"><span style="font-size: 10pt; font-family: "Verdana","sans-serif";">Ryan: I'm a little concerned with using hostnames
and not IP address in the System -> Server settings. Do you mean IP
addresses don't match what's on the box on the other side? In the event of
a DNS failure I don't want my phone system to go down. I understand that
there will be more and more dependancies, but I'd like to minimize them.</span></li>
<li class="MsoNormal" style="color: black;"><span style="font-size: 10pt; font-family: "Verdana","sans-serif";">Ryan: I'm a little confused as to you what you
mean by your last paragraph. How can I use hostnames if I haven't
configured DNS? Won't it come back with errors?</span></li>
<li class="MsoNormal" style="color: black;"><span style="font-size: 10pt; font-family: "Verdana","sans-serif";">Justin: I would think it would be cleaner to
delete and recreate rather than simply edit. </span></li>

Don't worry about network connectivity for accessing the DMA files, since
that's going to be during the install and no services will be running to either
accept connections or initiate them.</span></p>
<div>
<p class="MsoNormal"><span style="font-size: 10pt; font-family: "Verdana","sans-serif"; color: black;"> </span></p>
</div>
<div>
<p class="MsoNormal"><span style="font-size: 10pt; font-family: "Verdana","sans-serif"; color: black;">When changing the IP address I'd highly recommend your
System->Server entries be hostnames and not IP addresses, since bad things
happen when the IP address in System->Server doesn't match the one that's
actually on the box.</span></p>
</div>
<div>
<p class="MsoNormal"><span style="font-size: 10pt; font-family: "Verdana","sans-serif"; color: black;"> </span></p>
</div>
<div>
<p class="MsoNormal"><span style="font-size: 10pt; font-family: "Verdana","sans-serif"; color: black;">You are correct that you don't have to configure DNS or NTP until
after everything is built. In fact unless you are going to have a DNS
server on the dead network then you will cause problems by configuring a DNS
server.</span></p>
</div>
<div>
<p class="MsoNormal"><span style="font-size: 10pt; font-family: "Verdana","sans-serif"; color: black;"> </span></p>
</div>
<div>
<p class="MsoNormal"><span style="font-size: 10pt; font-family: "Verdana","sans-serif"; color: black;">Since the servers get their hosts files configured during the sub
install as long as no DNS is configured and your System->Server entries are
hostnames then you can leave the new servers on a live network (just with
different IPs than the production servers). They won't talk to anything
they can't resolve and without DNS the only thing they will resolve is the
other nodes of the cluster. You'll want to watch out for multicast MOH if
you do this, but otherwise it should be safe.</span></p>

<div>
<p class="MsoNormal"><span style="font-size: 10pt; font-family: "Verdana","sans-serif"; color: black;">The rest of your procedure looks fine, maybe a bit of overkill,
but definitely the safe way to go.</span></p>

Lelio,<br>
<br>
Are you planning to use new IP addresses for the entire cluster? if so, I
would do install the new publisher via DMA, select to use a new IP address on a
new isolated VLAN that doesnt have connectivity to your production
environment. Then once the ccmadmin page is up for the new publisher,
just go into the system>server menu and change the IP addresses from the
current 4.1/production IPs to the new addresses you've allocated to the new
cluster. Once you've changed the IPs of the
subscribers, I would reboot the system and then you should be fine to put it on
the production network.<br>
<br>
Renaming the IPs is much easier than deleting and recreated - since when you
delete you have to rebuild all the dependencies, etc. I've also had
problems in the past with the old server names / IPs staying around in some
system configuration files that have required TAC assistance to root in and
manually edit these files.<br>

<ol start="1" type="1">
<li class="MsoNormal" style="color: black;"><span style="font-size: 10pt; font-family: "Verdana","sans-serif";">install the new publisher using DMA with a new IP
address on a new VLAN</span></li>
<li class="MsoNormal" style="color: black;"><span style="font-size: 10pt; font-family: "Verdana","sans-serif";">reconfigure callmanager groups so they all use the

<li class="MsoNormal" style="color: black;"><span style="font-size: 10pt; font-family: "Verdana","sans-serif";">delete call park numbers on all subscribers</span></li>
<li class="MsoNormal" style="color: black;"><span style="font-size: 10pt; font-family: "Verdana","sans-serif";">remove all previous subscriber information from
the new publisher</span></li>
<li class="MsoNormal" style="color: black;"><span style="font-size: 10pt; font-family: "Verdana","sans-serif";">start installing the new subscribers</span></li>
<li class="MsoNormal" style="color: black;"><span style="font-size: 10pt; font-family: "Verdana","sans-serif";">rebuild callmanager groups and call park numbers</span></li>
</ol>
<p class="MsoNormal"><span style="font-size: 10pt; font-family: "Verdana","sans-serif"; color: black;">I'm not sure how I can do that on a dead network, since the
install process goes out and does DNS tests and NTP tests etc. Plus I need to
access my DMA upgrade file too, right?<br>
<br>
I guess I could skip enabling DNS, NTP, etc, until just before step 5 once I
put the publisher on a live network, and perform steps 1 thru 4 on an isolated
VLAN with SFTP access to my DMA file?<br>
<br>
What do you think?<br>

The CUCM servers themselves initiate connections to each other and I have seen
post-DMA servers initiating connections (SDL, media resources) to the 4.x
servers because they were reachable. I'd highly advise keeping your
post-DMA servers on a dead-net until you can get new IP addresses on
them. </span></p>

interruptions in our production network. Can anyone confirm that any traffic,
i.e. registration is end point initiated? We only have SCCP and MGCP and SRST
devices out there. There's no reason for the new cluster to try to talk to any
of the devices out there is there?<br>
