[cisco-voip] CM4.1.3-move publisher

[Voll, Scott]

Are all the CM's 7835's or better?
 
I would be temped to pull at drive out of all CM's (subs and pubs at all locations) leave everything running then once the drive got to the new location (New server at new location) have everyone put in the pulled drives.  That way the call managers would all be on the same page with out loosing EM, Forwarding, etc.  you would just loose the changes that day because you would overnight the drive of course.

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.
 
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.
