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>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>

I'd highly advise keeping your post-DMA servers on a dead-net until you can get new IP addresses on them. <div>

I want to make sure that we 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 cluster to try to talk to any of the devices out there is there?<br>
