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><span style="color: black;"></span></p>

<p class="MsoNormal" style=""><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><span style="color: black;"></span></p>

<p class="MsoNormal" style=""><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><span style="color: black;"></span></p>

<p class="MsoNormal" style=""><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><span style="color: black;"></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>

Our plan was to:</span><span style="color: black;"></span></p>
<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
publisher and only the publisher</span></li>
<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" style=""><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><span style="color: black;"></span></p>

don't cause any service 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
