<DIV><FONT face=Arial size=2>I think people have demonstrated with success the
ability to change an IP address, which may or may not be required in your case.
So you should be OK there. The two things I would worry about are the length of
time your publisher will be down and the features that are unavailable for that
time, i.e. forwarding/unforwarding of phones, extension mobility, IPCC agent
logings, etc. Database replication is another issue, the subscribers can get
into some state of disarray if the publisher is not available for an extended
period of time. I think a restart of the cluster and/or using the DBLhelper tool
may help you here.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>The most important thing is the latency between the
sites. A distributed cluster requires a specific maximum roundtrip delay between
cluster members so as long as that is OK, you should be good to go.</FONT></DIV>
