I installed the publisher without an NTP source (it sync'ed to the
hardware clock) and then when I tried to install a subscriber it
choked, said it couldn't contact the NTP server on the publisher. I
tried reconfiguring NTP on the publisher to the local switch, but I
don't think it liked it.</div>

ws: not likely, CM needs a stratum 3(?) or better source. See SRND.
Configuring stratum on router/switch is undesirable as NTP process will
monitor clock drift.<br>

Anyways, the subscriber installed terminated abruptly after I said

I'm not sure how to make the publisher believe the switch is a valid

ws: you can definitely add one from CLI. you may be able to do it from
platform web pages. Just give it a valid NTP reference. You can
restart NTP to expedite the sync. Use 'utils ntp status' and make sure
you're not seeing '*127.127.1.0' as this indicates you're still using
the internal clock.<br>

Regarding, the cluster itself...everything is new hardware - pub and
subs. The steps you point to refer to changing the IP address on the
subscribers, but they don't exist yet. This leads me to believe that
changing the IP addresses on the publisher is sufficient, then I begin
re-installing the subscribers with the new IP addresses.<br>
</div>

ws: Yep! Just re-ip your publisher. change it under system->server

Perhaps it will just be easier once the publisher is built and the IP
addresses are changed, to move it back to the production network,
configure a valid NTP source and start building the subscribers after
that?<br>
</div>
</blockquote>
ws: just need valid NTP source so clocks get in sync before database
tries to replicate.<br>

I'm <span>going through building a new cluster that I'd like to run
concurrently on my network with new IP addresses and CallManager names.
I have always used IP addresses and would like to continue using IP
addresses for now. I've installed 7.1(3a) along with a DMA import. Then
I applied 7.1(5) upgrade. No problems. I did this all in an isolated
switch with only the publisher and FTP server. <br>

ws: make sure you provide it a valid NTP reference, espcially if this
standalone will become a cluster.<br>

If you are looking to replace certain nodes within the cluster then
you will need to reinstall and restore those nodes from backup. This is
especially true if you are attempting to replace the publisher node in
an existing cluster.<br>
