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>
